Creator:: Tuma, Teresa K. Easterling
Abstract:: This collection consists of autobiographical essays which center around my father, my first husband, and my backyard. All of the pieces are recollections, and most occur either from my study inside the house, or from the deck outside, looking at the yard. The Preface is the story of how I...

Electrical properties of GaAs FET structures

Creator:: Yang, Fanling Hsu
Abstract:: The electrical properties of ion-implanted GaAs FET channels are investigated by two methods. First, the channel current (I) as a function of voltage (V) is examined at different temperatures and using different voltage ramp rates. The standard FET I-V curve, which can be observed on a commercial curve tracer, is...

Electo-optic characterization of ZnS:Tb ACTFEL devices for probing the hot electron distribution

Creator:: Streicher, Keone R.
Abstract:: In this report, the optical characteristics of ZnS:Tb AC driven thin-film electroluminescent devices are evaluated. Luminescence at low and room temperature under a constant phosphor field is recorded in order to probe the hot electron energy distribution. Samples fabricated by atomic layer epitaxy and by sputter deposition are investigated and...

A study of the photoresponse of semi-insulating gallium arsenide

Creator:: Schumm, Gerhard
Abstract:: The photoresponse behavior of semi-insulating GaAs is investigated. The photocarrier lifetime is discussed and the influence of surface and contact recombination is taken into account. Photocurrent-voltage characteristics have been measured and a mechanism for the gain in terms of space charge amplification and avalanching is suggested. The influence of deep...

Modeling of the orientation dependence of scanned HgCdTe infrared detectors

Creator:: Reudink, Mark D.
Abstract:: Mercury cadmium telluride is important in the detection of electromagnetic radiation in the eight to twelve micron atmospheric window for infrared imaging systems. High resolution infrared imaging systems use either large (256x256 element to 1024x1024 element) staring arrays or much smaller (1-6 element) scanned arrays in which the image is...

Modeling and testing of semi-insulating gallium arsenide interdigitated photodetectors

Creator:: Kollipara, Ravindranath Tagore
Abstract:: High speed photodetectors are a necessary element in broad band digital and analog optical communication systems. In this thesis easily integrable planar high speed photodetectors made on undoped semi-insulating (SI) GaAs substrates are modeled and tested. The fabrication process of the detectors is fully compatible with GaAs metal-semiconductor field effect...

Finite element modeling of dielectric waveguides

Creator:: Vishakhadatta, Gannavaram D.
Abstract:: Dielectric waveguides are becoming important for their numerous applications in integrated optics. The study of dielectric waveguides by analytical techniques is not sufficient for many variations in waveguide shape, anisotropy, and inhomogeneity commonly encountered in waveguide materials. This work studies the finite element method as an accurate tool for the...
