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…
