Next generation sequencing (NGS) is a disruptive technology that concurrently sequences millions of DNA fragments at low cost with high throughput and impacts nearly every field of biology and medicine. The most widely used biosensing techniques today, including those for NGS, are optical in nature and thus do not benefit from the annual scaling advancements made in the semiconductor industry. ISFETs...
This paper investigates the effect of nano-scale SiO2 on the tracking failure properties of nanocomposites. Test samples were made by dispersing nano-scale SiO2 powder in epoxy with the weight ratios of 0, 1, 3, 5, 7, 9 wt%. AC voltage was applied on a pair of needle-plate electrodes at the surface with the insulation distance of 10 mm. The time to tracking failure and discharge current were recorded...
High-power photo conductive semiconductor switches with a gap of 12 mm were fabricated from semi-insulating GaAs, in which carbon acceptor impurity was compensated by deep EL2 donor defect, resulting in very large dark resistivity. Triggered by laser pulse with different optical energy at wavelength of 1064 nm and 532 nm, photoconductivity tests of the PCSS at different bias voltage are underway....
Summary form only given. Super-powerful pulsed systems needs more accurate timing synchronization because more high voltage gas switches for higher pulsed power will be needed. Therefore triggering of high voltage gas switches will become a key factor affecting performance of pulsed systems. This paper reports on an experimental study of developing a photoconductive semiconductor switches (PCSS) to...
