Low-dimensional Materials for Next-generation Transistors
My first proposed research direction is to explore one-dimensional (1D) materials for next-generation gate-all-around (GAA) transistors. GAA Transistors are deemed the last stop of the Moore’s law, and its key is to create quasi-1D semiconductor channels with ideal interfaces. I will study both crystallographically and topologically defined 1D electronic systems.
Cryogenic Electronics Accelerating Classical/Quantum Computing
Current quantum computing hardware research overwhelmingly focuses on qubits and quantum processors, whereas the peripheral circuitry technologies are falling behind. The control and readout chain of qubits need to be redesigned for optimal performance in quantum applications at the sub-Kelvin temperature regime. Such components include, but are not limited to, cryo-CMOS, cryo-amplifiers, cryo-RF devices, quantum interconnect, and quantum packaging technologies. Electrical, mechanical, and thermal properties need to be considered under quantum principles when designing such cryogenic devices.
Chiral Topological Materials
Chirality is an overarching concept in quantum physics chemistry, and material science, and it has various definitions in, for instance, crystal structure, electronic structure, magnetic structures, etc. Our goal is to demystify the fundamental correlation between chirality and topology from a symmetry point of view in both real space and momentum space. This will allow us to exploit chirality as a new degree of freedom to design new device concepts such as spintronics and topological qubits.
