Band-gap engineering for removing shallow traps in rare-earth Lu3Al5O12 garnet scintillators using Ga3+ doping
Original language description
We employ a combination of first-principles calculations and optical characterization experiments to explain the mechanism by which Ga3+ doping prevents the trapping of free carriers due to shallow traps in RE3Al5O12 garnet scintillators (where RE represents a 3+ rare-earth cation). Specifically, we confirm that Ga3+ doping does not reduce the defect concentration (defect engineering), but rather leads to shifts in the valence and conduction bands such that the energy level of shallow defects is no longer in the forbidden gap where electrons can be trapped (band-gap engineering).
