Journal ArticleDOI
Oxygen vacancy tuned Ohmic-Schottky conversion for enhanced performance in β-Ga2O3 solar-blind ultraviolet photodetectors
Daoyou Guo,Zhenping Wu,Y. H. An,Xuncai Guo,Xulong Chu,Changlong Sun,Linghong Li,Peigang Li,Peigang Li,Weihua Tang +9 more
TL;DR: In this paper, metal/semiconductor/metal structured photodetectors were fabricated using as-grown film and annealed film separately, where the Schottky barrier controlled electron transport and the quantity of photogenerated carriers trapped by oxygen vacancy significant decreasing.
Journal ArticleDOI
β-Ga2O3/p-Si heterojunction solar-blind ultraviolet photodetector with enhanced photoelectric responsivity
Xuncai Guo,N.H. Hao,Daoyou Guo,Zhenping Wu,Y. H. An,Xulong Chu,Linghong Li,Peigang Li,Ming Lei,Weihua Tang +9 more
TL;DR: In this article, β -Ga 2 O 3 /Si p-n heterojunctions are formed as a deep ultraviolet (UV) solar-blind photodetector, and the corresponding external quantum efficiency is over 1.8 × 10 5 %.
Journal ArticleDOI
Review of gallium oxide based field-effect transistors and Schottky barrier diodes
Journal ArticleDOI
Unipolar resistive switching behavior of amorphous gallium oxide thin films for nonvolatile memory applications
Daoyou Guo,Zhenping Wu,Y. H. An,Peigang Li,Peigang Li,Wang Pengchao,Xulong Chu,Xuncai Guo,Yusong Zhi,Ming Lei,Linghong Li,Weihua Tang +11 more
TL;DR: Amorphous gallium oxide thin film with heavy oxygen deficiency was deposited on Pt/Ti/SiO2/Si substrate by pulsed laser deposition in order to explore the resistive switching behavior of the Pt/Ga2O3-x/Pt sandwich structure.
Journal ArticleDOI
Room temperature ferromagnetism in (Ga1−xMnx)2O3 epitaxial thin films
Daoyou Guo,Zhenping Wu,Y. H. An,Xiaojiang Li,Xuncai Guo,Xulong Chu,Changlong Sun,Ming Lei,Linghong Li,Lixin Cao,Peigang Li,Peigang Li,Weihua Tang +12 more
TL;DR: In this paper, Mn-doped monoclinic β-(Ga 1−xMnx)2O3 thin films were epitaxially grown on α-Al 2O3 (0001) substrates by alternately depositing Ga2O 3 and Mn layers using the laser molecular beam epitaxy technique.
