The semiconductor gallium arsenide (GaAs) has many potential
advantages over the more widely used semiconductor silicon (Si).
These include higher low field mobility, semi-insulating substrates,
a direct band-gap, and greater radiation hardness. All these
advantages offer distinct opportunities for implementation of new
circuit functions or extension of the operating conditions...
Transparent conductive oxides (TCOs), primarily indium doped tin oxide, have been widely used in numerous fields since decades ago, such as solar cells, displays, OLEDs and ‘smart windows’ etc. Owing to the scarcity of indium, there is a great demand for new alternative materials. Metal/insulator/metal (MIM) diodes are a critical...
Flexible electronics processing techniques were applied to integrate a glucose sensor with a hormone-delivery catheter in order to create a cheap and minimally invasive method for patients with type 1 diabetes to continually monitor and control their blood sugar levels. Ultimately, this work intends to move toward the development of...
It has become customary in electrical engineering to think of
signal processing in terms of voltage variables to the exclusion of
current variables. This tendency has resulted in voltage signal
processing circuits such as voltage-controlled voltage sources
(VCVS) and voltage-mode operational amplifiers. However, the VCVS
operational amplifier has several limitations...
The purpose of this study is to develop experimental techniques to
characterize typical interconnect discontinuities, including bends, steps, T
junctions, vias and pads, which are the most commonly encountered
interconnections in high speed digital integrated circuits, hybrid and
monolithic microwave circuits and electronic packages. The time domain
reflection response of...
The creation of new semi-interpenetrating polymer networks (semi-IPNs) was attempted using miscible blends of high molecular weight cellulose esters (CE) and low molecular weight polyvinylphenol (PVP) with various initiators for the crosslinking reaction. Blends of cellulose acetate (CA) or cellulose acetate butyrate (CAB), at 50/50, 70/30, and 90/10 wt%CE/wt% PVP...
