The effect of asymmetric lateral linking groups on the electronic transport is investigated in the biphenyl molecule-based device with gold electrodes with the framework of density functional theory and nonequilibrium Green’s function. The asymmetric lateral linking groups reduce the currents of molecular junctions, and result in the reverse rectifying behavior. The devices with asymmetric lateral linking groups –SH and –SCH3 have maximum rectifying ratios, while the asymmetric lateral linking group –SH and –NH2 cause minimum rectifying ratios. The calculated results suggest that the asymmetric lateral linking group induces the reduced coupling between molecule and right electrode, asymmetric distribution of frontier molecular orbital and asymmetric evolution of the molecular orbital eigenenergies, accounting for the rectifying behavior.

ABSTRACTFor measuring molecular device, we developed a dual-probe scanning tunneling microscope (D-STM) composed of two STM systems in which a carbon nanotube (NT) was used for STM tip. Using D-STM, we fabricated a NT ring device. The NT ring device showed a switching behavior with applying gate bias. Furthermore, in STM imaging for various gate biases, we could observe directly hole injection into the NT ring.

Purpose-This paper aims to investigate factors that affect customer switching from Internal Combustion Engine Vehicles (ICEV’s) to Hybrid Electrical Vehicles (HEV’s), in Jordan for the period of (2010-2014).Design/methodology/approach-A self-administered survey was hand-delivered to the targeted sample of car users in Jordan. The authors delivered 400 questionnaires to customers, from which 333 were deemed valid for the analysis, corresponding to the percentage of (83.25%) which indicates the validity of the study. Findings- There was no difference in switching behavior between (ICEV’s) and (HEV’s) based on gender in the Jordanian market. Fuel consumption efficiency was the number one variable that supports the switching behavior towards (HEV's), followed by Eco friendliness, lower taxes and technological features. Price and the current trend in the market were the least supporting factors. In addition to that the perception of the battery life of (HEV's), limited choices in the market, lack of information and fear of the relatively new technology were the major hindering factors of choosing an (HEV).Research limitations-Future research needs to investigate other factors that may affect customers’ behavior such as perceived image, trust, and subjective norms. Future research should investigate into the importance of environmental awareness and new technologies, and gender differences in behavior. From an international marketing standpoint, comparative studies between Jordanian and non-Jordanian customers are potential areas of future research for international marketing strategies and cross-cultural consumer behaviour analysis. Practical implications-The paper identifies the determinants of switching behavior. marketers should focus addressing customers concerns in terms of providing enough information and building awareness towards the technology and it's benefits towards the society and the environment.Originality/value-Our study is one of the few in Jordan that investigates the switching behavior towards vehicles technology. Our study is thought to have made a modest contribution to consumer behaviour literature and, specifically, for decision making process. It offers marketers insights into the determinants of switching behavior towards the hybrid vechicle technology and how this contribute to consumers’ decision making process and attitudes to achieve the intended behavioural outcomes

First observation of switching behavior is reported in GaAs metal-insulator-p-n+structure, where the thin insulator is grown at low temperature by a liquid phase chemical-enhanced oxide (LPECO) with a thickness of 100 Å. A significant S-shaped negative differential resistance (NDR) is shown to occur that originates from the regenerative feedback in a tunnel metal/insulator/semiconductor (MIS) interface andp-n+junction. The influence of epitaxial doping concentration on the switching and holding voltages is investigated. The switching voltages are found to be decreased when increasing the epitaxial doping concentration, while the holding voltages are almost kept constant. A high turn-off/turn-on resistance ratio up to105has been obtained.

AbstractIn this work, we report the formation of a new type of active or “smart” surface that is produced by ion implantation and thermal processing. By co-implanting vanadium and oxygen into a single-crystal sapphire substrate and annealing the system under appropriate conditions, it was possible to form buried precipitates of vanadium dioxide that were crystallographically oriented with respect to the host AI2O3 lattice. The implanted VO2 precipitate system undergoes a structural phase transition that is accompanied by large variations in the optical transmission which are comparable to those observed for thin films of VO2 deposited on sapphire. Co-implantation with oxygen was found to be necessary to ensure good optical switching behavior.
