讲座摘要/Abstract:

Since the advent of one-dimensional carbon nanotubes (CNTs) in 1991 and two-dimensional graphene in 2004, followed by transition metal dichalcogenides (TMDs), there has been an explosion of research exploring their unique fundamental science and technological applications. Among them, other 2D layered materials such as TMDs, hexagonal boron nitride (hBN), and black phosphorus (BP) have been extensively studied, opening new horizons in physics, electronics, and optoelectronics. These materials also offer exciting possibilities in emerging fields like valleytronics, spintronics, twistronics, and orbitronics. The key physics behind include strong Coulomb interactions, reduced charge screening, large exciton binding energies, and significant spin-orbit coupling, which present valuable opportunities for both fundamental research and practical applications. In this presentation, I will discuss recent and ongoing challenges in the field of vdW semiconductors and devices including Ohmic contact, mobility/on-current, hot-carrier solar cell, and Bose-Einstein condensation in electronics, ferromagnetic semiconductors at room temperature, etc.
