Summary on Grant Application Form |
|
The 12 year old argon ion laser, the only one in the group and department, failed catastrophically in early November. It is irreparable. It is an essential piece of equipment in our optical lab, which is used for experiments funded on 3 current EPSRC grants (GR/L19973 - Physics od Quantum Dots, GR/L95540 - Quantum Dot Lasers (NGLD Initiative) and GR/K96274 - Quantum Transport and Optical Phenomena). The two PDRAs on the first two grants use the laser and optical bench system daily, and have published/submitted 5 journals and 12 conference proceedings papers in the last year. A replacement laser is essential for these two programmes. Briefly, the laser is used for PL experiments on semiconductor heterostructures containing self-assembled quantum dots, grown in-house by MBE. PL spectra provide fundamental information about electron and hole energies in the QD and an estimate of the QD size, complementing atomic force microscopy measurements. PL data are also an essential for designing and optimising QD laser diodes. We recently started a series of experiments on photoexcited resonant tunnelling (RT) through quantum dots incorporated in the quantum well of an RT device. We also use the laser for our experiments on conventional RT devices and superlattices.
