Band Offsets at Strained-Layer Interfaces [PDF]
MRS Proceedings, 1987 ABSTRACTStrained-layer heterojunctions and superlattices have recently shown tremendous potential for device applications because of their flexibility for tailoring the electronic band structure. We present a theoretical model to predict the band offsets at both lattice-matched and pseudomorphic strained-layer interfaces.

Calculation of Band Offsets of Mg(OH)2-Based Heterostructures
Electronic Materials, 2021 The band alignment of Mg(OH)2-based heterostructures is investigated based on first-principles calculation. (111)-MgO/(0001)-Mg(OH)2 and (0001)-wurtzite ZnO/(0001)-Mg(OH)2 heterostructures are considered. The O 2s level energy is obtained for each O atom
