Moss-burstein effect

WebThe effect of Ta doping is the shift of the absorption band in the UV range towards higher energy values, suggesting a larger optical band gap with respect to bare TiO 2 films, due to the Moss–Burstein effect (see next section). 50,51 In the visible range, all ε 2 curves are close to zero, suggesting no absorption as expected for TiO 2 and TiO 2-based TCOs. WebApr 10, 2024 · Another reason for increasing the Eg of Zn 0.97 Gd 0.03 O rather than the value of ZnO is the Moss–Burstein effect . Because the Gd atoms are donors, Zn 0.97 Gd 0.03 O can be represented as an n-type semiconductor. According to many researchers, including Kabongo, the energy gap of Zn 0.97 Ho 0.03 O was greater than that of ZnO .
