Daoyou Guo,Zhenping Wu,Peigang Li,Y. H. An,Han Liu,Xuncai Guo,Hui Yan,G. F. Wang,Changlong Sun,Linghong Li,Weihua Tang +10 more
TL;DR: In this article, a laser molecular beam epitaxy technology was employed to deposit β-gallium oxide (β-Ga2O3) on (0001) sapphire substrates.
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
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.
