Investigation of copper chloride for photonics applications

Abstract

Wide band gap semiconductors have found multiple applications. Being light emitters in the range of blue and UV, materials like GaN or ZnO have been applied to highly efficient blue light emitting diodes, and increasingly popular high power and efficient white light emitters or blue lasers. Due to significant lattice mismatches with their substrates both GaN and ZnO suffer from a large number of material defects. Advanced growth techniques allowed us to achieve satisfactory results, but at the cost of fabrication simplicity, which has impacted on the production cost. Another interesting property of wide band-gap semiconductors is high exciton binding energy.
