GaAs doped by self-assembled molecular monolayers
Zhengfang Fan, Yumeng Liu, Yizuo Wang +3
Self-assembled molecular monolayer doping remains as a research focus for its nature of being conformal, nondestructive, and self-limiting. Herein, we demonstrate a sulfur monolaye…
Reproducible Monolayer MoS2 Devices Free of Resist Contamination by Gold Mask Lithography
Yumeng Liu, Yizhuo Wang, Zhengfang Fan +4
Atomically thin MoS2 is a promising material for field-effect transistors (FETs) and electronic devices. However, traditional photolithographic processes introduce surface contamin…
Defects in graphite engineered by ion implantation for the self-assembly of gold nanoparticles
Yumeng Liu, Yanhao Deng, Yizhuo Wang +8
Defect engineering in two-dimensional (2D) materials is essential for advancing applications such as gas sensing, single-atom catalysis, and guided nanoparticle self-assembly, enab…
High Performance MoS2 Phototransistors Photogated by PN Junction
Seyed Saleh Mousavi Khaleghi, Jianyong Wei, Yumeng Liu +4
Photodetectors based on two-dimensional (2D) atomically thin semiconductors suffer from low light absorption, limiting their potential for practical applications. In this work, we…
Analytical photoresponses of Schottky contact MoS2 phototransistors
Jianyong Wei, Yumeng Liu, Yizhuo Wang +10
High-gain photodetectors based on two-dimensional (2D) semiconductors, in particular those in photoconductive mode, have been extensively investigated in the past decade. However,…
