In brief

Abstract

PAGE 105 The transient off-state thermal emission leakage currents of hydrogenated amorphous silicon and indium gallium zinc oxide metal oxide thin-film transistors fabricated on flexible plastic substrates have been examined by researchers in the US. They have also shown that the observed transient leakage currents result in a shot noise that is twenty times larger than predicted using only conventional static leakage current measurements. PAGE 111 Researchers in the UK have presented an RF energy harvesting technique for powering small devices. Their work focuses on harvesting power from ambient radio waves, which is particularly useful in sensor networks where energy requirements are low and appeals as a solution to make them self-sustaining. The observed shot noise was 20 times greater than static leakage current measurements predicted PAGE 107 The first experimental demonstration of a continuous wave two-pump fibre optic parametric amplifier has been reported by researchers in France. Their device is of primary interest in the amplification of chirped pulses, and should allow for an all-fibre parametric amplifier operating at 1 µm with a flat gain band. The RF energy harvesting technique is aimed at allowing self-sustaining sensor networks PAGE 98 Researchers in Korea have devised a simple and cost-effective epitaxial graphene fabrication technique that results in good electric performance. This approach is expected to pave the way for a more cost-effective formation of highly reliable, low sheet resistance graphene, particularly for SiC-based electronic devices, power devices, SiC-graphene hetero-junctions and graphene-on-insulator semiconductors. The amplifier uses a dispersion stabilised microstructured optical fibre with high nonlinearity and low loss PAGE 93 Researchers in France have realised and measured an innovative microwave transmission line which can be integrated into complex multilayer systems. A multilayer structure like transmission line is essential to any telecommunication and radar power devices, such as power modules, solid state power transmitters, filters or any distribution system in that frequency range. A simpler and cheaper way to make graphene with low sheet resistance Thermal simulations suggest the structures will handle 50W average RF powers making them suitable for x-band power combination
