Optoelectronic modulation spectroscopy (OEMS) has been used to reveal defect states in 4H-SiC. Pairs of magnitude and phase spectra have been used to infer whether they were electron or hole traps. Eleven discrete trap responses have been observed, e

Undoped 28 nm AlGaN on 1 μm GaN was grown by MOVPE for high power microwave HFETs. Non-destructive methods for rapid characterisation of the layers are described. Double contact mercury probe capacitance voltage measurements gave valuable informatio

The effects on the insulator-semiconductor interface of two different deposition methods of silicon nitride on In0.53Ga0.47As have been electronically studied using capacitance-voltage (CV) and deep level transient spectroscopy (DLTS) measurements. T

An experiment using the phenomenon of percolation has been conducted to demonstrate the implementation of neural functionality (summing and sigmoid transfer). A simple analog approximation to digital percolation is implemented. The device consists of

Excimer laser microetching is applied on various substrate materials, including metals, metal alloys, semiconductors, and polymers, of arbitrary geometrical shape for fabricating surface-relief optical microstructures with very fine features (micron
