Origin of Symmetric Dimer Images of Si(001) Observed in Low-Temperature STM
Xiao-Yan Ren, Hyun-Jung Kim, Chun-Yao Niu +2
It has been a long-standing puzzle why buckled dimers of the Si(001) surface appeared symmetric below 20 K in scanning tunneling microscopy (STM) experiments. Although such symmetr…
Atomically thin binary V-V compound semiconductor: a first-principles study
Weiyang Yu, Zhili Zhu, Chun-Yao Niu +2
Searching the novel 2D semiconductor is crucial to develop the next-generation low-dimensional electronic device. Using first-principles calculations, we propose a class of unexplo…
Dilute magnetic semiconductor and half metal behaviors in 3d transition-metal doped black and blue phosphorenes: a first-principles study
Weiyang Yu, Zhili Zhu, Chun-Yao Niu +3
We present first-principles density-functional calculations for the structural, electronic, and magnetic properties of substitutional 3d transition metal (TM) impurities in two-dim…
