Schottky Photodiode

Small area metal semiconductor metal (MSM) photodiode (PD) has been one of the most favoured detector choices for high speed optoelectronics integrated circuits due to their low parasitic capacitance and simple planar device structure, which is compatible with FETs. Large MSM PDs, on the other hand, can also be useful in many network and interconnect applications such as fibre distributed data interfaces. An MBE grown GaN metal semiconductor metal photodiode with a thin low temperature GaN (50nm) barrier enhancement layer is reported, which has low dark current. The detector using Nickel ( Ni ) Schottky metal fingers with 400 μm spacing on a large active area exhibit a low dark current of 1.23 mA at 10 V bias, which is about three orders of magnitude lower than that of the normal GaN Schottky photodiode.

Printing Processes

Recently low cost production is vital to produce printed electronics by roll to roll manufacturing printing process like a flexographic. Flexographic has a high speed technique which commonly used for printing onto large area flexible substrates. However, the minimum feature sizes achieved with roll to roll printing processes, such as flexographic is in the range of fifty microns. The main contribution of this limitation is photopolymer flexographic plate unable to be produced finer micron range due to film that made by Laser Ablation Mask (LAMs) technology not sufficiently robust and consequently at micron ranges line will not be formed on the printing plate. Hence, polydimethylsiloxane (PDMS) is used instead of photopolymer. Printing trial had been conducted and multiple solid lines successfully printed for below fifty microns line width with no interference between two adjacent lines of the printed images.

AbstractDiffuse Coplanar Surface Barrier Discharge (DCSBD) is a novel type of atmospheric-pressure plasma source developed for high-speed large-area surface plasma treatments. The statistical behavior of microdischarges of DCSBD generated in artificial air atmosphere was studied using time-correlated optical and electrical measurements. Changes in behavior of microdischarges are shown for various electrode gap widths and input voltage amplitudes. They are discussed in the light of correlation of the number of microdischarges and the number of unique microdischarges’ paths per discharge event.The ‘memory effect’ was observed in the behavior of microdischarges and it manifests itself in a significant number of microdischarges reusing the path of microdischarges from previous half-period. Surprisingly this phenomenon was observed even for microdischarges of the same half-period of the discharge, where mechanisms other than charge deposition have to be involved. The phenomenon of discharge paths reuse is most pronounced for wide electrode
