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...

Dissertation
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...

Masters Thesis
Characteristics of semi-insulating GaAs photoconductive detectors under steady state illumination

Creator:

Yang, Howard C.

Abstract:

The optical and electrical characteristics of semi-insulating GaAs photoconductive detectors made with ohmic and Schottky contacts are studied in this thesis. Current - voltage measurements are made both in the dark and under varying power levels of HeNe laser (6328 Å) illumination. DC photocurrent gain is then calculated as a...

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...

Dissertation
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...

Masters Thesis
Wide stripe, high power diode lasers

Creator:

Parson, Kevin J.

Abstract:

Typical power outputs of commercially available diode lasers are on the order of 5 milliwatts. This thesis discusses the growth, processing and fabrication of high power (lOO's of milliwatts) diode lasers. Devices were grown by Molecular Beam Epitaxy (MBE) and by Metal Organic Chemical Vapor Deposition (MOCVD). The MOCVD diode...

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...
