In this paper, we perform coupled optical and electrical simulation for core–shell junction GaAs nanowire array solar cells to obtain the important physical insights of how the cell efficiency is affected by various key parameters, including core–shell doping, junction position, carrier lifetime, and surface effect. Our study reveals that junction design in core–shell nanowires in terms of doping...
F2F stacking provides an alternative 3D packaging solution for multi-chip integration without use of TSV. High density interconnection can be achieved with direct Face-to-Face (F2F) stacking to enable high bandwidth die to die interface. Simplified stacking process and lower development cost make F2F stacking an attractive solution for cost sensitive applications. A comparative study of performance...
The galvanic corrosion behavior of conductive silicon rubber (CSR) couples with different alloys (aluminum alloy, nickel-plated aluminum alloy) were investigated in 3.5% sodium chloride solutions in sealed container by means of electrochemical measurement, weight-loss determination, and surface characterization. It was found that weight-loss method couldn't be the only way to evaluate the corrosion...
Charpy impact behaviors of eutectic SnBi solder joints with and without presence of Joule heating effect were investigated by employing a pendulum-type impact tester. The temperature rise induced by Joule heating effect at joined region can reach to 6.2°C and 1.7°C when the applied electric current was 10 A and 5 A, respectively. In addition, the temperature distribution of solder joints during the...
A laser generation and optical difference detection method of surface acoustic waves is used for characterizing elastic constants of thin films deposited on substrates. The film/substrate samples are prepared by a RF magnetron sputtering technique. Teflon-like films, deposited on three kinds of substrates, silicone plates, glass and copper plates, have been studied and the related parameters have...
Love-mode immunosensors based on ZnO/36degYX-LiTaO3 structures are studied. The ZnO films are grown on the 36degYX-LiTaO3 substrates by RF magnetron sputtering technique. The crystalline structures of the ZnO films are investigated by the X-ray diffraction (XRD) analysis, which show that the highly orientated (002) films are obtained. Then the Love-mode sensors are fabricated for monitoring antibody-antigen...
In this paper, a kind of Love wave sensors with SiO2/36degYX LiTaO3 structures for monitoring antibody-antigen immunoreactions in aqueous solutions in real time is presented. In this study, the devices with low insertion losses are achieved when the devices are in direct contact with the solutions. In the immunosensing measurements, a goat anti human-immunoglobulin G (HigG) is immobilized on the device...
