Modeling of Channel Potential and Subthreshold Slope of Symmetric Double-Gate Transistor (2009)

Ray, Biswajit, Mahapatra, Santanu

A new physically based classical continuous potential distribution model, particularly considering the channel center, is proposed for a short-channel undoped body symmetrical double-gate transistor....

Modeling and Analysis of Body Potential of Cylindrical Gate-All-Around Nanowire Transistor (2008)

Ray, Biswajit, Mahapatra, Santanu

A new physically based classical model for the potential distribution of an undoped body cylindrical gate-all-around nanowire transistor is proposed. The model is based on the analytical solution of...

Pump induced Autler-Townes effect and A-T mixing in a four level atoms (2004)

Bhattacharyya, Dipankar, Ray, Biswajit, Ghosh, Pradip N.

It is shown by theoretical simulation that tuning of the pump power can induce mixing and crossing of Autler-Townes(A-T)components of closely spaced transitions in atoms. Pump radiation also leads to...

Gain without inversion in a V-type system with low coherence decay rate for the upper levels (2004)

Bhattacharyya, Dipankar, Ray, Biswajit, Ghosh, Pradip N.

Inversionless gain is observed in a V-type inhomogeneously broadened system without introducing any incoherent pumping and only by changing the collisional dephasing decay rate. In this system...
