Performance And Characterization Of A Large Format Solid State Imager, Jacob A. Mendez Nov 2006

Performance And Characterization Of A Large Format Solid State Imager, Jacob A. Mendez

Electrical and Computer Engineering ETDs

The purpose of this thesis is to validate the specifications of the CCD 486 as specified by Fairchild Imaging, the manufacturer of the CCD and Spectral Instruments, the manufacturer of the camera control electronics and supporting hardware. Specifications have been provided by both companies and are shown in Appendix A. This study is necessary because of the nature of the experiments to be analyzed using the CCD 486. In addition, the thesis will propose new testing methods for electronically shuttered CCD imagers that are not well understood.


Mid-Infrared Multiple Quantum Well Lasers Using Digitally-Grown Allnassb Barriers And Strained Inassb Wells, Leslie G. Vaughn Jul 2006

Mid-Infrared Multiple Quantum Well Lasers Using Digitally-Grown Allnassb Barriers And Strained Inassb Wells, Leslie G. Vaughn

Electrical and Computer Engineering ETDs

Alxln(1-x)AsySb(1-y)quaternary alloys have been used in Type I midwave infrared (MWIR) laser structures as barrier materials with lnAs and InAsSb quantum wells. However, growth of these alJoys has limited the application because of a large miscibi lity gap. In this research, quaternary films with compositions well into the miscibility gap (0

Combining the quaternary bandgap equation with strain and quantum size effects. the wavelengths for strained lnAsSb wells in AllnAsSb quaternary barriers are predicted and compared to measured values generated from PL experiments. The reasonable agreement of these experimental results with the …
