Tmd heterojunction phd thesis
WebIn the liquid junction geometry, the TMD heterojunction is deposited on a conducting electrode and immersed in a redox electrolyte. The solid electrode and redox electrolyte make intimate electrical contact to the TMD components and enable efficient perpendicular charge separation and transport pathways over large areas. WebOct 24, 2024 · A growth technique to directly prepare two-dimensional (2D) materials onto conventional semiconductor substrates, enabling low-temperature, high-throughput, and large-area capability, is needed to realize competitive 2D transition-metal dichalcogenide (TMD)/three-dimensional (3D) semiconductor heterojunction devices.
