Estimation of Field Alfalfa Evapotranspiration in a Windy, Arid Environment

Author(s) : Barker, J. Burdette
Description : Evapotranspiration (ET) of center pivot irrigated alfalfa was studied in the windy, arid, Curlew Valley, Northern Box Elder County, Utah, during the summers of 2009 and 2010. ET was estimated using eddy covariance (EC) and surface renewal (SR) techniques. ET estimates from the EC and SR analyses wer...

Soft sphere model for electron correlation and scattering in the atomistic modelling of semiconductor devices

Author(s) : Watling, J.R. , Barker, J.R. , Asenov, A.
Description : The atomistic modelling of silicon MOSFET devices becomes essential at deep sub-micron scales when it is no longer possible to represent the charged impurities by a continuous charge distribution with a determined doping density. Instead the spatial distribution and the actual number of dopants must...

Efficient hole transport model in warped bands for use in the simulation of Si/SiGe MOSFETs

Author(s) : Watling, J.R. , Asenov, A. , Barker, J.R.
Description : An analytical geometric model for the valence band in strained and relaxed Si1-xGex is presented, which shows good agreement with a 6-band k·p analysis of the valence band. The geometric model allows us to define an effective mass tensor for the warped valence band structure. The model also has appl...

RF analysis methodology for Si and SiGe FETs based on transient Monte Carlo simulation

Author(s) : Roy, S. , Kaya, S. , Asenov, A. , Barker, J.R.
Description : A comprehensive analysis methodology allowing investigation of the RF performance of Si and strained Si:SiGe MOSFETs is presented. It is based on transient ensemble Monte Carlo simulation which correctly describes device transport, and employs a finite element solver to account for complex device ge...

Complete Monte Carlo RF analysis of 'real' short-channel compound FET's

Author(s) : Babiker, S. , Asenov, A. , Cameron, N. , Beaumont, S. P. , Barker, J. R.
Description : A comprehensive RF analysis technique based on ensemble Monte Carlo (EMC) simulation of compound FET's with realistic device geometry is presented. Y-parameters are obtained through Fourier transformation of the EMC transients in response to small changes in the terminal voltages. The terminal curre...

Scaling study of Si and strained Si n-MOSFETs with different high-k gate stacks

Author(s) : Yang, L. , Watling, J. R. , Adam-Lema, F. , Asenov, A. , Barker, J. R.
Description : Using ensemble Monte Carlo device simulations, this paper studies the impact of interface roughness and soft-optical phonon scattering on the performance of sub-100nm Si and strained Si MOSFETs with different high-k gate stacks. Devices with gate lengths down to 25nm have been investigated.

Nonequilibrium hole transport in deep sub-micron well-tempered Si p-MOSFETs

Author(s) : Watling, J.R. , Zhao, Y.P. , Asenov, A. , Barker, J.R.
Description : Using 2D full-band MC simulations the authors study nonequilibrium transport effects and the performance potential of well tempered Si p-channel MOSFETs covering gate lengths ranging from 90nm to 25nm. By comparing MC simulations with carefully calibrated drift diffusion (DD) simulations of the same...

Monte Carlo investigation of optimal device architectures for SiGe FETs

Author(s) : Roy, S. , Kaya, S. , Babiker, S. , Asenov, A. , Barker, J.R.
Description : Strained silicon channel FETs grown on virtual SiGe substrates show clear potential for RF applications, in a material system compatible with silicon VLSI. However, the optimisation of practical RF devices requires some care. 0.1-0.12 μm gate length designs are investigated using Monte Carlo techniq...

Strain engineered InxGa1-xAs channel pHEMTs on virtual substrates: a simulation study

Author(s) : Babiker, S. , Asenov, A. , Roy, S. , Barker, J.R. , Beaumont, S.P.
Description : The impact of InxAl1-xAs strain control buffers on the performance of low In content InGaAs channel pseudomorphic high electron mobility transistor p(HEMT) is investigated. It is shown that relaxed and tensile strained channel devices outperform the conventional compressively s...
