Electrically driven spin resonance (EDSR) is an established tool for controlling semiconductor qubits. Here, we theoretically study a frequency-mixing variant of EDSR, where two driving tones with different drive frequencies are applied, and the condition connects Larmor frequency sum frequencies. Focusing on flopping-mode operation single electron in double quantum dot spin-orbit interaction, ...

This review, dedicated to the memory of B. K. Sadashiva, concerns electrically driven patterns and defects in bent core nematics (BCNs) made hard-core, soft-core or bent-rod type molecules. It covers (a) spatially periodic associated with electroconvection flexoelectric deformation, (b) dislocations these patterned states (c) various types induced essentially homogeneous, unpatterned BCNs. Whil...

Electrically driven organic lasers are among the best lasing devices due to their rich variety of emission colors as well as other advantages, including printability, flexibility, and stretchability. However, electrically driven lasing in organic materials has not yet been demonstrated because of serious luminescent efficiency roll-off under high current density. Recently, we found that the org...

Introduction: The realisation of Si-based, electrically driven light emitters is a key requirement for the implementation of low-cost Si-based optoelectronics [1]. Realising Si-based light sources in a process technology compatible with mainstream microelectronics technology is one of the big challenges of semiconductor technology. Because of its indirect bandgap Si has a low radiative recombin...

A vapor–liquid–solid (VLS) growth of microwhiskers was developed by Wagner et al. in the 1960s. The recent re-examination of this method by the groups of Lieber, Yang, Samuelson, Wang, and others has resulted in the flourishing research into nanowires (NWs). Nearly all the IV, II– VI, III–V, and IV–VI semiconductor NWs can be synthesized. Ternary compound semiconductors have also been demonstra...

In this paper, we present a novel concept and primary investigations regarding automated unfastening of hexagonal nuts by means surface exploration with compliant robot. contrast to the conventional industrial approaches that rely on custom-designed motorised tools mechanical tool changers, propose use robot fingers position, grasp unfasten unknown random-sized nuts, which are arbitrarily posit...

Cerium oxides have attracted much attention because of their uses in three-way catalysts and other catalyst applications. The redox reaction of cerium oxides, as the basis of their use as catalysts, usually takes place at high temperature (>600 K) and/or low oxygen partial pressure. There have been continuous efforts to lower the operating temperatures of cerium oxide further to improve the per...
