[Abstract]

Essentially all electronic devices that we use today are based on inorganic single-crystalline semiconductors such as Si, GaN, and GaAs, which offer the highest speed, efficiency, sensitivity, and lifetime. However, conventional semiconductor devices are intrinsically/physically bonded   to wafers that are thick (0.5- 1 mm) and rigid, which limits their application in emerging technologies such as biodegradable/flexible/ three-dimensional electronics. In this talk, I will introduce advanced manufacturing strategies for next- generation electronics based on Layer Transfer technology, which enables the production of freestanding single-crystalline semiconductor device layers by separating them from their epitaxial wafers. This allows distinct opportunities for developing electronic systems that can: (i) completely dissolve in biofluids at physiological pH/temperatures, (ii) conformally adhere on skin to enable convenient, nearly imperceptible human-computer interface, or (iii) achieve ultrahigh device density and versatility through 3D integration of disparate functional layers. More specifically, I will discuss applications such as bioresorbable implantable medical devices, chipless wireless electronic skins, and vertical micro-LEDs for AR/VR display.

[Short Biography]

Jiho Shin is currently a research scientist at the Massachusetts Institute of Technology (MIT), but he will start as an assistant professor at Texas A&M University starting August 2024. He has a broad research background in micro/nanofabrication, electronic/optoelectronic/photonic/MEMS devices, IV/III-V/III-N semiconductor materials, and implantable/wearable electronics. As a postdoc/research scientist in Jeehwan Kim group at MIT, he is leading projects in three-dimensional heterogeneous integration of single-crystalline III-V/III-N compound semiconductor membranes for micro-LED display and neural interface applications.

Before joining MIT, he received his B.S. and Ph.D. in Chemical Engineering from Cornell University and the University of Illinois at Urbana-Champaign, respectively. During his Ph.D. study in John Rogers group, he developed bioresorbable intracranial MEMS/optical/photonic sensors using single-crystalline silicon nanomembranes. He has published 21 peer-reviewed articles including 6 first-authored papers in journals   
such as Nature, Science, Nature Nanotechnology, and Nature Biomedical Engineering.
