Abstract:

My group's general interests are in the area of nanostructured semiconductor materials and devices. We focus on developing innovative structures and device concepts through bottom-up epitaxial growth and top-down fabrication approaches to bring lasting impact to the field of electronics, photonics, and quantum technologies; and potentially medicine. In this talk, I will present two of the nanofabrication platforms we innovated recently and aim to address some of the pressing issues in nanofabrication and applications:  (1) an unorthodox anisotropic etching method, metal-assisted chemical etching (MacEtch), that enables site-controlled semiconductor nanostructure top-down fabrication with unprecedentedly high aspect ratio and materials and structure versatility;1-3 and (2) a 3D self-rolled-up membrane (S-RuM) nanotechnology platform for extreme miniaturization of passive electronic components, including inductors, transformers, and filters, for radio frequency integrated circuits (RFICs) and power electronics.4,5 I will also present, if time allows, several examples of heterogeneous epitaxy including selective-area and van der Waals epitaxy.
