Date Feb 12, 2025, 12:30 pm – 1:30 pm Details Event Description Some Materials Engineering Experiments for Heterogeneous Integration of Thin Films for Microelectronics and Quantum TechnologiesAbstract: Heterogeneous integration of different materials to create integrated chip scale packages has enabled new capabilities in microelectronics; such an approach may have potential advantages for future quantum technologies as well. In this talk I will describe a few ongoing experiments in my group aimed at establishing new heterogeneous integration methods for future applications. These are: (i) the spalling of “hard” materials such as SiC, diamond, and Yttrium Iron Garnet/Gadolinium Gallium Garnet (YIG/GGG) for power electronics and quantum technologies; (ii), our work on “direct-write” physical vapor deposition and chemical vapor deposition where we miniaturize an evaporator on chipand place it on a near field scanning stage—the intent here is to enable 3D write capabilities for microelectronics with mesoscale and lower resolutions; (iii), initial results from an imprint crystallization technique we are developing that would enable single crystal films on arbitrary substrates through localized solid phase epitaxy; (iv) the study of Er doped thin film oxides on silicon for chip scale quantum emitters. My talk will focus on the materials science aspects of these experiments and I will address both the “good news” and the bad.Bio: Supratik Guha is a professor at the Pritzker School of Molecular Engineering at the University of Chicago, a Senior Scientist at Argonne National Labs, and the CTO of the DOE Q-NEXT center on quantum interconnects led by Argonne. Prior to this he was at IBM Research where he last served as Director of Physical Sciences till 2015. He is a materials scientist, with research interests in materials and systems for future information processing.
