2023年11月1日 · Here we present RT ferromagnetism in an Fe-doped SnSe (Fe:SnSe) van der Waals (vdW) single crystalline ferromagnetic semiconductor (FMS) with a semiconducting bandgap of ∼1.19 eV (comparable to those of Si and GaAs).

2019年6月18日 · Using a low-temperature scanning tunneling microscope (STM), we investigated the role of atomic-scale defects of a cleaved SnSe(100) surface on the electronic structure around them. We found in empty-state STM images that Sn vacancies induce dark contrast around them, proving their role as a p-type dopant.

2024年9月6日 · Tin selenide (SnSe) nanorods were synthesized using a one-step solvothermal route and their humidity sensing and photodetection performance at room temp. were investigated. The results depict that SnSe nanorod-based humidity and photosensors have good long-term stability, are highly sensitive and have fast response and recovery times.

2023年5月24日 · Here, we present a combined experimental and theoretical study of the atomic structure and electronic properties of epitaxial SnSe structures grown on a metallic Au (111) substrate, forming almost defect-free 2D layers. We describe a coverage-dependent transition from a metallic β -SnSe to a semiconducting α -SnSe phase.

2020年4月1日 · Here, we applied STM/STS to investigate thin films of picene molecules on a semiconductor substrate, SnSe, under ultrahigh vacuum (UHV) conditions. By comparing the structural and electronic properties of picene films on SnSe and on Au (1 1 1), it is found that the interaction between picene thin film and SnSe is weakened.

2016年9月1日 · Herein, for the first time, the atomic and electronic structures of SnSe surfaces are studied by a home-built low temperature scanning tunneling microscope (STM) and density functional theory (DFT) calculations. The cleaved surface of SnSe is comprised of covalently bonded Se and Sn atoms in zigzag patterns.
