Table 2 Structural relaxations around each oxygen vacancy and average distances from the defect positions to neighboring ions.
From: Effects of oxygen vacancies on the structural and optical properties of β-Ga2O3
Vacancy type | Distance in Å (the Ga coordination number around O vacancy which is shown in Fig. 1 (b), +denotes Ga ions move close, while −denotes Ga ions move away) | |||
