A simple DNA-based nanomechanical device is presented which can be switched between three different conformations by the addition of appropriate signal molecules. Two of these conformations are mechanically rigid. The device consists of two arms formed by double-stranded DNA, connected by a singlestranded hinge. The device can be in a closed or stretched configuration, and in an intermediate re...

This paper projects the enhanced drive current of a ntype electrostatically doped (ED) tunnel field-effect transistor (ED-TFET) based on heterojunction and band-gap engineering via TCAD 2-D device simulations. The homojunction ED-TFET device utilizes the electrostatic doping in order to create the source/drain region on an intrinsic silicon nanowire that also felicitates dynamic re-configurabil...

The use of carbon nanotubes for field effect nanoelectronic devices, which has been recently demonstrated, motivates further studies of electrochemical and chemical analogues of nanotube molecular transistors. However, chemical gating is not applicable for modern electronics due to its slow response. Herein we propose a novel molecular electronic device: Nanotube LightControlled Switch (NLCS). ...

Abstract Converting mechanical energy from either the ambient environment or human body motions to useful electrical will revolutionize power solutions for flexible electronics. Here, a hybrid harvesting strategy is reported, which combines porous polymeric piezoelectric film with an electrostatic layer as integration converting into energy. The materials through engineered microstructures are ...

This article discusses an electron energy analyzer with a cylindrically symmetrical electrostatic field, designed for rapid Auger analysis. The device was designed and built. The best parameters of the analyzer were estimated and then experimentally verified.

Pulsed energization of electrostatic precipitator (ESP) may represent one of the most promising solutions to comply with strict environmental regulation in case of high resistivity dust. Performs a parametric cost comparison between conventional and pulsed ESP with reference to four main industrial areas: electric power generation, cement manufacturing, iron and steel production, glass industry...

This paper reports on a visual servoing system capable of 2DOF nanopositioning using a novel multi-axis electrostatic MEMS (MicroElectroMechanical System) device. The high aspect ratio micromanipulator was fabricated using a high yield process with Deep Reactive Ion Etching (DRIE) on Silicon-On-Insulator (SOI) wafers, which produces larger electrostatic forces and requires lower actuation volta...

Carbon nanotube transistors have outstanding potential for electronic detection of biomolecules in solution. The physical mechanism underlying sensing however remains controversial, which hampers full exploitation of these promising nanosensors. Previously suggested mechanisms are electrostatic gating, changes in gate coupling, carrier mobility changes, and Schottky barrier effects. We argue th...

Physical phase plates (PP) for transmission electron microscopy (TEM) are intensively studied since the first carbon film-based and electrostatic PPs have been experimentally realized [1,2]. By inducing a phase shift on a part of the electrons in the back focal plane of the objective lens, contrast enhancement can be achieved. Several groups have already demonstrated proof-of-principle experime...
