Atomic layer etching of electronic and quantum materials

Abstract:
Future electronic and quantum devices will require near-atomically-precise nanofabrication processes, but present plasma processing methods create a variety of imperfections that limit device performance. In this talk, I will present atomic layer etching processing for materials including superconducting titanium nitride, lithium niobate, and compound semiconductors which enable etching with Angstrom-scale precision. I will also describe our efforts to validate the process improvements at the device level.

Abstract:
New tools of light for increasingly refined observation and control of molecules are providing new opportunities to study complex structure and emergent quantum properties, to set new bounds for fundamental symmetry, to probe real-time reaction kinetics, and to apply molecular sensing for medical diagnosis. Meanwhile, quantum gases of molecules constitutes an outstanding experimental platform for precise quantum state engineering and control of inter-molecular interactions, enabling exploration of novel chemical reactions and quantum magnetism
