摘要:
A device for patterning structures on a substrate includes an imaging device having a scanning tip, a light emitting device, and a space around the scanning tip. The space comprises a vapor of a material which is suitable for Chemical Vapor Deposition onto the substrate when decomposed. The light emitting device is adapted to emit a light beam, which has an intensity not capable to decompose the vapor, onto the scanning tip in such a way that an electromagnetic field induced by the light beam near the scanning tip is high enough to decompose the vapor.

A MOS device includes first and second source/drains spaced apart relative to one another. A channel is formed in the device between the first and second source/drains. A gate is formed in the device between the first and second source/drains and proximate the channel, the gate being electrically isolated from the first and second source/drains and the channel. The gate is configured to control a conduction of the channel as a function of a potential applied to the gate. The MOS device further includes an energy filter formed between the first source/drain and the channel. The energy filter includes an impurity band operative to control an injection of carriers from the first source/drain into the channel.

A method of forming nanowire devices. The method includes forming a stressor layer circumferentially surrounding a semiconductor nanowire. The method is performed such that, due to the stressor layer, the nanowire is subjected to at least one of radial and longitudinal strain to enhance carrier mobility in the nanowire. Radial and longitudinal strain components can be used separately or together and can each be made tensile or compressive, allowing formulation of desired strain characteristics for enhanced conductivity in the nanowire of a given device.

A multi-terminal programmable element. The programmable element includes a source electrode and a drain electrode on a base. The programmable element includes reference voltage contact that is not in contact with the source or drain electrode. The base includes a transition-metal oxide with oxygen vacancies for drifting under an applied electric field. Further, materials of the source electrode and the base are selected such that an interface of a source and/or drain electrode material and the transition metal oxide base material forms an energy barrier for electron injection from the electrode into the base material. The energy barrier has a height that depends on an oxygen vacancy concentration of the base material. Four non-volatile states are programmable into the programmable element.
