The rapid proliferation and diffusion of large language model driven agentic inference continue to fuel an unprecedented demand for semiconductors for high-performance compute. Addressing this compute demand goes beyond just CMOS logic transistor scaling and requires a system-driven rethink of semiconductor research. In this talk, we explore emerging semiconductor technology pillars essential for the next […]

A 6 eV bandgap crystal used to be a textbook example of an electrical insulator. But today it has become possible to make pn diodes, transistors, LEDs, and lasers with ultrawide bandgap nitride semiconductors. In the first part of my talk, I will discuss how over the last 25 years, we have discovered a powerful […]

Abstract: The first part of this talk reviews the central role of response functions in single- and multiplescattering theories of light, together with the limitations imposed by their conventional formulation in the time-harmonic regime. I will then show how spectral expansions of response functions, and the closely related theory of Quasi-Normal Modes provide a natural […]
