| 3 | Toward emerging gallium oxide semiconductors:A roadmap显示文摘Owing to the advantages of ultra-wide bandgap and rich material systems,gallium oxide(Ga_(2)O_(3))has emerged as a highly viable semiconductor material for new researches.This article mainly focuses on the growth processes,material characteristics,and applications of Ga_(2)O_(3).Compared with single crystals and the epitaxial growth of other wide-bandgap semiconductors,large-size and high-quality��-Ga_(2)O_(3) single crystals can be efficiently grown with a low cost,making them highly competitive.Thanks to the availability of high-quality single crystals,epi-taxial films,and rich material systems,high-performance semiconductor devices based on Ga_(2)O_(3) go through a booming development in recent years.The defects and interfaces of Ga_(2)O_(3) are comprehensively analyzed owing to their significant influence on practical applications.In this study,the two most common applications of Ga_(2)O_(3) materials are introduced.The high breakdown electric field,high working temperature,and excellent Baliga’s figure-of-merit of Ga_(2)O_(3) represent an inspiring prospect for power electronic devices.In addition,the excellent absorption in deep-ultraviolet band provides new ideas for optoelectronic detectors and ensures the dramatic progress.Finally,the summary,challenges,and prospects of the Ga_(2)O_(3) materials and devices are presented and discussed. | Yuan Yuan Weibing Hao Wenxiang Mu Zhengpeng Wang Xuanhu Chen Qi Liu Guangwei Xu Chenlu Wang Hong Zhou Yanni Zou Xiaolong Zhao Zhitai Jia Jiandong Ye Jincheng Zhang Shibing Long Xutang Tao Rong Zhang Yue Hao | 2021 | Fundamental Research2021，1，6： | 5 |
| 4 | A review of β-Ga_2O_3 single crystal defects, their effects on device performance and their formation mechanism显示文摘As a wide-bandgap semiconductor(WBG), β-Ga_2O_3 is expected to be applied to power electronics and solar blind UV photodetectors. In this review, defects in β-Ga_2O_3 single crystals were summarized, including dislocations, voids, twin, and small defects. Their effects on device performance were discussed. Dislocations and their surrounding regions can act as paths for the leakage current of SBD in single crystals. However, not all voids lead to leakage current. There's no strong evidence yet to show small defects affect the electrical properties. Doping impurity was definitely irrelated to the leakage current. Finally, the formation mechanism of the defects was analyzed. Most small defects were induced by mechanical damages. The screw dislocation originated from a subgrain boundary. The edge dislocation lying on a plane slightly tilted towards the(102) plane, the(101) being the possible slip plane. The voids defects like hollow nanopipes, PNPs, NSGs and line-shaped grooves may be caused by the condensation of excess oxygen vacancies, penetration of tiny bubbles or local meltback. The nucleation of twin lamellae occurred at the initial stage of 'shoulder part' during the crystal growth. These results are helpful in controlling the occurrence of crystal defects and improving the device performance. | Bo Fu Zhitai Jia Wenxiang Mu Yanru Yin Jian Zhang Xutang Tao | 2019 | Journal of Semiconductors2019，40，1： | 5 |

| 9 | Rapid epitaxy of 2-inch and high-quality α-Ga_(2)O_(3) films by mist-CVD method显示文摘High thickness uniformity and large-scale films of α-Ga_(2)O_(3) are crucial factors for the development of power devices.In this work, a high-quality 2-inch α-Ga_(2)O_(3) epitaxial film on c-plane sapphire substrates was prepared by the mist-CVD method.The growth rate and phase control mechanisms were systematically investigated. The growth rate of the α-Ga_(2)O_(3) films was limited by the evaporation of the microdroplets containing gallium acetylacetonate. By adjusting the substrate position(z) from 80 to 50 mm, the growth rate was increased from 307 nm/h to 1.45 μm/h when the growth temperature was fixed at 520 °C.When the growth temperature exceeded 560 °C, ε-Ga_(2)O_(3) was observed to form at the edges of 2-inch sapphire substrate.Phase control was achieved by adjusting the growth temperature. When the growth temperature was 540 °C and the substrate position was 50 mm, the full-width at half maximum(FWHM) of the rocking curves for the(0006) and(10-14) planes were 0.023° and 1.17°. The screw and edge dislocations were 2.3 × 10~6 and 3.9 × 10~(10)cm~(-2), respectively. Furthermore, the bandgaps and optical transmittance of α-Ga_(2)O_(3) films grown under different conditions were characterized utilizing UV-visible and near-IR scanning spectra. | Xiaojie Wang Wenxiang Mu Jiahui Xie Jinteng Zhang Yang Li Zhitai Jia Xutang Tao | 2023 | Journal of Semiconductors2023，44，6： | 1 |

| 17 | Investigation on the key factors in the hydrothermal synthesis of BN: The way of introducing sodium azide显示文摘The way of introducing sodium azide (NaN_3) into the reaction solution played an important role in the preparation of cBN by hydrothermal synthesis method. The results showed that both cBN content and crystalline perfection of the samples improved with increasing R_N value, and pure cBN could be obtained at 300℃ and 10 MPa when R_N increased to 3:1. Here R_N is defined as R_N =NaN_3(I)/NaN_3(II), wherNaN_3(I) denotes the amount of NaN_3 (in molar) that is added into the autoclave at the beginning of threaction process, and NaN_3(II) is the amount of NaN_3 (also in molar) introduced into the autoclave ahigh temperature and high pressure (i.e. 300℃ and 10 MPa). In order to explain the experimental results, a preliminary model was proposed in this paper. | LI Kai JIANG HaiHui LIAN Gang WANG QiLong ZHAO Xian CUI DeLiang TAO XuTang | 2007 | Chinese Science Bulletin2007，52，13： | 1 |
