In fact, new materials, such as Ge, with higher effective mobilities of electrons (2times) and holes (4times) than in Si are already being explored to increase the drive currents in MOSFETs. In addition, by straining the Ge channels, it is possible to further increase the mobilities of the holes. However, how this advantage in mobility translates to improved drive current in the short-channel length MOSFETs is not completely clear. For example, in the ballistic limit, it is thermal velocity that matters (Lundstrom, 1997) and these are comparable for Si and Ge. Although, there have been reports from some experimental and theoretical (in the ballistic limit) studies of the mobility and drive current enhancements of unstrained and strained Ge channel MOSFETs over Si MOSFETs, no Monte Carlo simulation taking into account full band structure, scattering, non local field effects, etc., has so far been been performed. The aim of this work was to perform a full band Monte Carlo simulation study of unstrained Ge bulk N- and P- MOSFETs and strained Ge bulk PMOSFETs and compare with their Si counterparts. Since biaxial strain along the (100) plane in Ge does not break the degeneracy of the conduction band L valleys of Ge, we have not considered strained Ge NMOSFETs","PeriodicalId":306160,"journal":{"name":"63rd Device Research Conference Digest, 2005.

In the coming years portable systems will demand even more NVM with high density and very high writing throughput for data storage application, or with fast random access for code execution. Flash memory has followed the scaling evolution, of the semiconductor map since its introduction in the late '80's but further scaling is becoming increasingly complex as some of the fundamental physical limitations are being approached. While continued research on floating gate techniques should extend the current flash technology capability through the end of this decade, there is increasing interest in new memory storage mechanisms and materials that have promise for scaling through at least the end of the next decade. Among the different NVM based on storage mechanisms alternative to the floating gate concept, phase-change memories (PCM), also called ovionic unified memory (OUM),is one of the most promising candidates, having the potential to improve the performance compared to flash as well as to be scalable beyond flash technology (Lai and Lowrey (2001), Lai (2003), Bez (2004)), In this review, the physics and operation of phase change memory is first presented, followed by discussion of current status of development.

Prototype planar TCTs were fabricated with resonantly-coupled dual-channel InAlAs/InGaAs/InP HEMT heterostructures by providing independent electrical contacts to each channel. The current-voltage characteristics are determined by an interwell and intersubband tunneling.
