ZnO/MO_x Nanofiber Heterostructures: MO_x Receptor’s Role in Gas Detection by Vadim Platonov, Oleg Sinyashin, Marina Rumyantseva

“…It was demonstrated that the temperature of the maximum sensor response of ZnO/MO_x nanofibers toward reducing gases is primarily influenced by the binding energy of chemisorbed oxygen with the surface of the modifier’s oxides. When detecting oxidizing gas NO₂, high sensitivity at a low measurement temperature can be achieved with a high concentration of free electrons in the near-surface layer of zinc oxide grains, which is determined by the band bending at the ZnO/MO_x interface characterized by the difference in the electron work function of ZnO and MO_x.…”

First‐Principles Study of Twin Boundaries and Stacking Faults in β‐Ga2O3 by Mengen Wang, Sai Mu, James S. Speck, Chris G. Van de Walle

“…In spite of their higher energies, TBs and SFs on planes other than (100) have been experimentally observed in epitaxial layers. Their origins are explained in terms of coalescence of different growth regions when the growth direction changes, or when low‐energy TBs on the growing surface lead to domains with different twinning orientation.…”
