11.3 μm InAs/GaAs quantum dot lasers on silicon with GaInP upper cladding layers显示文摘We report on the first electrically pumped continuous-wave(CW) In As/Ga As quantum dot(QD) laser grown on Si with a GaInP upper cladding layer. A QD laser structure with a Ga_(0.51)In_(0.49)P upper cladding layer and an Al_(0.53)Ga_(0.47)As lower cladding layer was directly grown on Si by metal–organic chemical vapor deposition. It demonstrates the postgrowth annealing effect on the QDs was relieved enough with the GaInP upper cladding layer grown at a low temperature of 550°C. Broad-stripe edge-emitting lasers with 2-mm cavity length and 15-μm stripe width were fabricated and characterized. Under CW operation, room-temperature lasing at ~1.3 μm has been achieved with a threshold density of 737 A∕cm^2 and a single-facet output power of 21.8 mW.JUN WANG HAIYANG HU HAWING YIN YIMING BAI JIAN LI XIN WEI YUANYUAN LIU YONGQING HUANG XIAOMIN REN HUIYUN LIU 2018Photonics Research2018,6,4:2
2On division management for environmental system of China: lessons from European local sustainable development显示文摘The concept of sustainable development, after being brought forward, has become a shibboleth in the world, at national and local levels. In Europe, this concept is implemented from the local to the nation, even to the Continent. The local sustainable development mainly consists in two factors: one is the renovating method continually invented by European Secretariat of ICLEI, and the other is that the local authorities towards sustainability are co-operated by the European Sustainable Cities and Towns Campaign. The eco-budget method is the outcome of these factors. For our country is a big country on rapid progression of industrialization and urbanization, with a large population and scarce resources per capita, it is practically significance to study as soon as possible the methodology. Experience from European local sustainable development may help us to resolve the handicap of department division in local authority.Bai Yongqing Hao Jingxia Zhu Xiancheng 2006Ecological Economy2006,2,2:1
3Programmable robotized‘transfer-and-jet’printing for large,3D curved electronics on complex surfaces显示文摘Large,3D curved electronics are a trend of the microelectronic industry due to their unique ability to conformally coexist with complex surfaces while retaining the electronic functions of 2D planar integrated circuit technologies.However,these curved electronics present great challenges to the fabrication processes.Here,we propose a reconfigurable,mask-free,conformal fabrication strategy with a robot-like system,called robotized‘transfer-and-jet’printing,to assemble diverse electronic devices on complex surfaces.This novel method is a ground-breaking advance with the unique capability to integrate rigid chips,flexible electronics,and conformal circuits on complex surfaces.Critically,each process,including transfer printing,inkjet printing,and plasma treating,are mask-free,digitalized,and programmable.The robotization techniques,including measurement,surface reconstruction and localization,and path programming,break through the fundamental constraints of 2D planar microfabrication in the context of geometric shape and size.The transfer printing begins with the laser lift-off of rigid chips or flexible electronics from donor substrates,which are then transferred onto a curved surface via a dexterous robotic palm.Then the robotic electrohydrodynamic printing directly writes submicrometer structures on the curved surface.Their permutation and combination allow versatile conformal microfabrication.Finally,robotized hybrid printing is utilized to successfully fabricate a conformal heater and antenna on a spherical surface and a flexible smart sensing skin on a winged model,where the curved circuit,flexible capacitive and piezoelectric sensor arrays,and rigid digital–analog conversion chips are assembled.Robotized hybrid printing is an innovative printing technology,enabling additive,noncontact and digital microfabrication for 3D curved electronics.YongAn Huang Hao Wu Chen Zhu Wennan Xiong Furong Chen Lin Xiao Jianpeng Liu Kaixin Wang Huayang Li Dong Ye Yongqing Duan Jiankui Chen Hua Yang Wenlong Li Kun Bai Zhouping Yin Han Ding 2021International Journal of Extreme Manufacturing2021,3,4:1
