| Abstract: | Semiconductor photonic emitters operating in the UV range remain an elusive goal. Attention has focused mainly on Ill-Nitrides. However, a large lattice constant difference between the Ill-Nitride layers and the compatible substrates results in high densities of misfit dislocations and consequently the device performance is adversely affected. An alternative novel material system, γ-CuCl on silicon, is investigated. Properties of the exciton luminescence from vacuum deposited undoped and oxygen doped CuCl films on Si are studied using temperature dependent photoluminescence spectroscopy. Oxygen doping degrades the optical quality and introduces an intermediate state leading to negative thermal quenching behaviour. |
