The effects of roadbuilding, logging and burning upon stream
runoff responses to individual storms are evaluated for the Alsea
experimental watersheds, located in the Oregon Coast Range, The
parameters analyzed are peak discharge, induced peak discharge,
time-to-peak, and storm-runoff volume. The volume parameter is
further sub-divided into total, quick, delayed,...
This paper analyzes the theory and performance of a
Schottky barrier diode detector used over a frequency range
extending from a few kilohertz into the gigahertz region.
The process of large signal rectification is analyzed with
the simplified detector circuit. Phenomena which can
affect the rectification process at high frequencies,...
The properties of evaporated aluminum-oxide films were investigated. The characteristics of MOS devices
made with single-layer aluminum-oxide films and double-layer
films which were made by evaporating aluminum oxide
over thermally-grown silicon dioxide as gate insulation
have been investigated. Vacuum-evaporated aluminum oxide
has features which are suitable for fabricating MOS devices....
This thesis is an experimental study of an acoustic
surface wave delay line using a Lithium Niobate crystal.
A brief theory of operation of the interdigital transducer
with its advantages over the other methods of exciting and
detecting acoustic surface waves is discussed. The experimental
procedure used for evaluation of...
The theoretical aspects and fabrication techniques of
a new surface field-effect transistor were investigated.
The new MOS-transistor uses a three-layer structure
similar to those found in bipolar transistors. The new MOS
structure introduces an impurity gradient in the channel
region of the transistor and also makes it possible to reduce...
In this work the use of linear MOS integrated circuits in the
design of a phase-shift oscillator is presented. By multiplying the
capacitors of the RC feedback network through the use of the Miller
effect, large effective capacitance values are obtained which enable
the low frequency operation of the oscillator....
The influence of surface fields on the breakdown voltage
is studied experimentally for p⁺-n silicon diodes with
a junction depth of 0.5μ in order to improve the curvature-
limited breakdown of the diffused, shallow-collector
junction of a microwave transistor.
Devices with a gap in the gate metal electrode are
also...
The MOS tetrode transistor is studied in this project.
This device is ideally suited for high frequency and
switching application.
In effect it is the solid state
analogy of a multigrid vacuum tube performing a very useful
multigrid function.
A new structure is developed for
p-channel 10 ohm-cm. silicon substrate...
The use of double-diffused n-type MOS transistor
(DN-MOS) in a complementary MOS random-access-memory (CMOS
RAM) cell is the main objective of this investigation.
DN-MOS transistors and conventional p-channel MOS
transistors on the same chip have been successfully fabricated.
Process sequence effects on device threshold voltage
and channel length are discussed....
