First-principles study on the magnetic properties in Mg dooped BiFeO3 with and without oxygen vacancies
Vacancies Magnesium Magnetic moments Antiferromagnetism Band gap
2016/12/2
The magnetic properties of Mg-doped BiFeO3 (BFO) with and without oxygen vacancies are studied through first-principles calculations. The Mg-doping prefers to occupy the ferromagnetic planes and produ...
New structural model for GeO2/Ge interface: A first-principles study
New structural model for GeO2/Ge interface first-principles study
2010/11/24
First-principles modeling of a GeO2/Ge(001) interface reveals that sixfold GeO2, which is derived from cristobalite and is different from rutile, dramatically reduces the lattice mismatch at the inter...
