Nobel Prize in Physics in 2000 2026-10-18
For foundational work in information and communication technology, Zhores I. Alferov and Herbert Kroemer received one quarter each for developing semiconductor heterostructures used in high-speed electronics and optoelectronics. Jack S. Kilby received one half for his part in inventing the integrated circuit.[ref]

Quantum well 2026-10-18
A quantum well confines a particle in one spatial direction while allowing motion along the layer. In a semiconductor heterostructure, band offsets can create that confinement. The following finite square well model makes the resulting discrete transverse energy levels explicit.
Semiconductor heterostructure 2026-10-18
A semiconductor heterostructure combines different semiconductors, using their interfaces and spatially varying band gaps to control device behavior.[ref]
