III-V quantum dots and wells

Quantum confined structures are utilised in a variety of applications due to the quantum confinement effect which forms the basis for improved device characteristics. The mature epitaxy technology has allowed us to grow quantum well and dot structures with unique electronic and optical properties.

Research in this field in the department revolves around the growth quantum dots and/or quantum wells for use as the (i) gain medium in metamaterials, (ii) absorption layers in third generation solar cells, (iii) absorption region in quantum dot infrared photodetectors and (iv) active region in high power lasers.
