Abstract:
In this chapter, we review the recent literature on scanning tunneling microscopy/scanning tunneling spectroscopy (STM/STS) and angle-resolved photoemission spectroscopy (ARPES) characterization of 2D semiconductor materials, focusing on 2D transition metal dichalcogenides (TMDCs) and mono-elemental 2D materials. After the introduction, we provide a brief description of the working principles of the STM and ARPES techniques, highlighting some of their advantages and limitations. We next discuss the fundamental atomic and electronic properties of 2D TMDCs (e.g., MoS2, MoSe2, and WSe2) characterized by STM/STS and ARPES/spin-resolved ARPES, to elucidate their exotic layer-dependent properties. In addition, we highlight some recent progress achieved on 2D mono-elemental materials, including silicene, black phosphorus, antimonene. We conclude this chapter with a forward-looking perspective on the future scientific challenges and developments in this field.
