| 3 | Development of Ultra-High Density Silicon Nanowire Arrays for Electronics Applications显示文摘This article reviews our recent progress on ultra-high density nanowires(NWs)array-based electronics.The superlattice nanowire pattern transfer(SNAP)method is utilized to produce aligned,ultra-high density Si NW arrays.We fi rst cover processing and materials issues related to achieving bulk-like conductivity characteristics from 1020 nm wide Si NWs.We then discuss Si NW-based fi eld-effect transistors(FETs).These NWs&NW FETs provide terrifi c building blocks for various electronic circuits with applications to memory,energy conversion,fundamental physics,logic,and others.We focus our discussion on complementary symmetry NW logic circuitry,since that provides the most demanding metrics for guiding nanofabrication.Issues such as controlling the density and spatial distribution of both p-and n-type dopants within NW arrays are discussed,as are general methods for achieving Ohmic contacts to both p-and n-type NWs.These various materials and nanofabrication advances are brought together to demonstrate energy effi cient,complementary symmetry NW logic circuits. | Dunwei Wang Bonnie A.Sheriff Michael McAlpine James R.Heath | 2008 | Nano Research2008，1，1： | 7 |
| 4 | Test Data Generation for Multiple Paths Based on Local Evolution显示文摘Generating test data by genetic algorithms is a promising research direction in software testing, among which path coverage is an important test method. The efficiency of test data generation for multi-path coverage needs to be further improved. We propose a test data generation method for multi-path coverage based on a genetic algorithm with local evolution. The mathematical model is established for all target paths, while in the algorithm the individuals are evolved locally according to different objective functions. We can improve the utilization efficiency of test data. The computation cost can be reduced by using fitness functions of different granularity in different phases of the algorithm. | YAO Xiangjuan GONG Dunwei WANG Wenliang | 2015 | Chinese Journal of Electronics2015，24，1： | 4 |

| 6 | Kinetically-Induced Hexagonality in Chemically Grown Silicon Nanowires显示文摘Various silicon crystal structures with different atomic arrangements from that of diamond have been observed in chemically synthesized nanowires.The structures are typified by mixed stacking mismatches of closely packed Si dimers.Instead of viewing them as defects,we define the concept of hexagonality and describe these structures as Si polymorphs.The small transverse dimensions of a nanowire make this approach meaningful.Unique among the polymorphs are cubic symmetry diamond and hexagonal symmetry wurtzite structures.Electron diffraction studies conducted with Au as an internal reference unambiguously confirm the existence of the hexagonal symmetry Si nanowires.Cohesive energy calculations suggest that the wurtzite polymorph is the least stable and the diamond polymorph is the most stable.Cohesive energies of intermediate polymorphs follow a linear trend with respect to their structural hexagonality.We identify the driving force in the polymorph formations as the growth kinetics.Fast longitudinal elongation during the growth freezes stacking mismatches and thus leads to a variety of Si polymorphs.The results are expected to shed new light on the importance of growth kinetics in nanomaterial syntheses and may open up ways to produce structures that are uncommon in bulk materials. | Xiaohua Liu Dunwei Wang | 2009 | Nano Research2009，2，7： | 2 |

| 13 | Mechanisms of water oxidation on heterogeneous catalyst surfaces显示文摘Water oxidation,an essential step in photosynthesis,has attracted intense research attention.Understanding the reaction pathways at the electrocatalyst/water interface is of great importance for the development of water oxidation catalysts.How the water is oxidized on the electrocatalyst surface by the positive charges is still an open question.This review summarizes current advances in studies on surface chemistry within the context of water oxidation,including the intermediates,reaction mechanisms,and their influences on the reaction kinetics.The Tafel analyses of some electrocatalysts and the rate-laws relative to charge consumption rates are also presented.Moreover,how the multiple charge transfer relies on the intermediate coverage and the accumulated charge numbers is outlined.Lastly,the intermediates and rate-determining steps on some water oxidation catalysts are discussed based on density functional theories. | Xiaogang Yang Yuanxing Wang Chang Ming Li Dunwei Wang | 2021 | Nano Research2021，14，10： | 1 |
| 14 | Dependence of interface energetics and kinetics on catalyst loading in a photoelectrochemical system显示文摘Solar hydrogen production by the photoelectrochemical method promises a means to store solar energy.While it is generally understood that the process is highly sensitive to the nature of the interface between the semiconductor and the electrolyte,a detailed understanding of this interface is still missing.For instance,few prior studies have established a clear relationship between the interface energetics and the catalyst loading amount.Here we aim to study this relationship on a prototypical Si-based photoelectrochemical system.Two types of interfaces were examined,one with GaN nanowires as a protection layer and one without.It was found that when GaN was present,higher Pt loading (> 0.1 μg/cm2) led to not only better water reduction (and,hence,hydrogen evolution) kinetics but also more favorable interface energetics for greater photovoltages.In the absence of the protection layer,by stark contrast,increased Pt loading exhibited no measurable influence on the interface energetics,and the main difference was observed only in the hydrogen evolution kinetics.The study sheds new light on the importance of interface engineering for further improvement of photoelectrochemical systems,especially concerning the role of catalysts and protection layers. | Yumin He Srin ivas Vanka Tianyue Gao Da He Jeremy Espano Yanyan Zhao Qi Dong Chaochao Lang Yongjie Wang Thomas W.

| 15 | A review of intelligent optimization for group scheduling problems in cellular manufacturing显示文摘Given that group technology can reduce the changeover time of equipment,broaden the productivity,and enhance the flexibility of manufacturing,especially cellular manufacturing,group scheduling problems(GSPs)have elicited considerable attention in the academic and industry practical literature.There are two issues to be solved in GSPs:One is how to allocate groups into the production cells in view of major setup times between groups and the other is how to schedule jobs in each group.Although a number of studies on GSPs have been published,few integrated reviews have been conducted so far on considered problems with different constraints and their optimization methods.To this end,this study hopes to shorten the gap by reviewing the development of research and analyzing these problems.All literature is classified according to the number of objective functions,number of machines,and optimization algorithms.The classical mathematical models of single-machine,permutation,and distributed flowshop GSPs based on adjacent and position-based modeling methods,respectively,are also formulated.Last but not least,outlooks are given for outspread problems and problem algorithms for future research in the fields of group scheduling. | Yuting WANG Yuyan HAN Dunwei GONG Huan LI | 2023 | Frontiers of Engineering Management2023，10，3： | 0 |
