Persistent Photoinduced Changes in Charge States of Donors and Acceptors in Hydrothermally Grown ZnO
Bulk ZnO grown by the hydrothermal technique was investigated using electron paramagnetic resonance (EPR), photoluminescence (PL), and infrared absorption (FTIR) techniques. Isolated subsitutional lithium is t...

Shallow donor generation in ZnO by remote hydrogen plasma
We investigate the effects of a remote hydrogen-plasma treatment on Hall parameters as well as on the bound exciton (BEx) photoluminescence (PL) for a variety of ZnO single crystals: bulk air-annealed, Li-dope...
