It was the intent of this investigation to compare the performance
of community college students to four-year institutional students, both
of whom were enrolled in a college general biology program (GS 101,
102, 103) during the 1967-68 academic year. During the week of
May 27, 1968 measurements were taken of...
The properties of flash- evaporated films of GaAs
and GaP were studied in this investigation. Films were
grown at various substrate temperatures, source temperatures,
source-to-substrate distances and rates of deposition
and were evaluated as to their structural,
optical and electric properties.
It was found that substrate temperature was the
major...
In this paper, the theory of metal-semiconductor contacts was
applied to metal contacts on gallium arsenide. A model was discussed
which proposed that the contact resistance was due to a highly
resistive region between the metal and the semiconductor. In order
to evaluate this resistance, a technique using a VHF...
Some important factors that affect the dimensional
control of oxide films on silicon were studied. Both N- and
P-type silicon with resistivities in the range of
0.014 to 200 ohm-cm and a (111) surface orientation
were employed in this experiment. The etching rates of
silicon dioxide in hydrofluoric acid (111)...
This thesis describes the adder to be used with the Galaxy computer, which is to be constructed at Oregon State University.
The need for faster, more reliable adders is discussed
along with previous adder designs related to the
Galaxy Fast Carry Adder.
Both the logical design and circuit design of...
