In this talk, I will delve into the concept that "the interface is the device," as famously stated by Dr. Herbert Kromer, Nobel Laureate in Physics in 2000, renowned for his contributions to semiconductor heterostructures in high-speed and opto-electronics. I will discuss our approach to designing advanced functional material interfaces, known as heterostructures, using computational methods based on first-principles quantum mechanics calculations, high-throughput computational techniques, and open quantum materials databases. Specifically, I will share our recent research progress on designing two-dimensional electron gas at interfaces between insulating perovskite oxides and achieving perpendicular magnetic anisotropy at interfaces between ferromagnets and insulating barriers.
