Dynamics of Charge and Energy Transport at Organic-Inorganic Semiconductor Heterojunctions
Abstract
The objective of this proposal is to explore fundamental properties of charge and energy transport across broad class of organic-inorganic semiconductor heterojunctions through modeling, engineering of materials, structures and morphologies. The PI proposes to conduct a comprehensive and systematic investigation of the physical mechanisms governing both energy and charge transport in hybrid organic/inorganic semiconductor hetero-junctions. He proposes to develop a comprehensive quantum description of the hybrid charge transfer exciton (HCTE) theory to determine the optimal materials combinations and film morphologies to maximize charge transfer across interfaces. The PI proposes to grow inorganic quantum wells (QW) and quantum dots at the semiconductor surfaces. The synthesis of organic/inorganic QWs will be done by using a combination of molecular beam epitaxy growth (MBE) along with ultrahigh vacuum process of organic molecular beam deposition (OMBD). Organic film morphology will be varied by using a process of organic vapor phase deposition (OVPD). He also proposes to grow QW structures on wide energy gap metal oxides such as ZnO, gallium and indium based oxides by using atomic layer deposition (ALD). Artificially engineered two dimensional van der Waals solids of organic/inorganic heterostructures will also be investigated as well.
