Abstract: Two-dimensional (2D) transition metal dichalcogenides (TMDCs) are a class of layered van der Waals (vdW) semiconductors that exhibit remarkable properties, including an optical bandgap, high carrier mobility, and tunable electronic properties. These properties,particularly in TMDC heterostructures, make them attractive for future optoelectronic technologies such as tunneling diodes, tunneling transistors, light-emitting diodes, and photovoltaic cells. TMDC devices based on homo- or heterostructures may consist of multi-layered stacks, each layer with a different elemental composition, resulting in devices with diverse properties. With increasing interest in this field and the potential to fabricate TMDC-based devices with multiple configurations, there is enormous potential for exploration, which could uncover interesting phenomena. In this direction, this thesis aims to investigate and provide a thorough understanding of the electronic band structure of WSe2, an important TMDC semiconductor, using a combination of angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) techniques.
