Summary on Grant Application Form |
|
A novel non-equilibrium liquid phase epitaxial growth technique - rapid slider liquid phase epitaxy (RSLPE) - will be developed and used to grow lattice-matched InAs quantum wells within the active region of an InAsSbP LED. We expect to obtain efficient electroluminescence from light emitting diodes which operate at one or more of the following wavelengths: 2.7?m (H20), 3.3?m (CH4), 3.7?m (H2S) 4.2?m (CO2), at room temperature and with high internal quantum efficiency. These sources are to be used primarily in the next generation of gas sensor instruments to improve health and safety in the environment and the quality of life. RSLPE has the advantage of being able to grow a wider range of lattice-matched quantum wells in mixed ternary and quaternary antimonide systems which are not readily accessible by conventional MBE or MOVPE. Strained InGaAs and InAsSb wells will also be investigated to further improve LED performance by suppressing non-radioactive Auger recombination.
