The energy band alignment of Si nanocrystals in SiO2 [PDF]
Applied Physics Letters, 2011 The determination of the energy band alignment between the 2.6-nm-diameter Si nanocrystals and the SiO2 host is achieved by means of photo-ionization/-neutralization and capacitance spectroscopy. The measured conduction and valence band offsets are 2.6 eV and 4.4 eV. The band gap is evaluated to be 1.7 eV by photoluminescence.

Bias dependent band alignment in Ga2O3 ferroelectric interface by operando HAXPES [PDF]
Scientific ReportsWe present a fundamental study of the band alignment at the interface of HfZrO4 (HZO) with Ge-doped Ga2O3. Ge is an alternative n-type dopant for the wide band gap Ga2O3 due to its shallow donor level and favorable MBE growth conditions.

Band alignment of B0.14Al0.86N/Al0.7Ga0.3N heterojunction [PDF]
Applied Physics Letters, 2017 Owing to large bandgaps of BAlN and AlGaN alloys, their heterojunctions have the potential to be used in deep ultraviolet and power electronic device applications. However, the band alignment of such junctions has not been identified. In this work, we investigated the band-offset parameters of a B0.14Al0.86 N/Al0.7Ga0.3N heterojunction grown by ...
