Synchronous polarization switching at sub-coercive fields through stochastic resonance in ferroelectric thin-film capacitors
Vivek Dey, Thejas Basavarajappa, Manikantan R. S. +4
Stochastic resonance (SR) is a phenomenon by which the presence of noise in a non-linear system allows for detection of a weak sub-threshold signal, or in a bi-stable system allows…
Analysis of Ferroelectric Negative Capacitance-Hybrid MEMS Actuator Using Energy-Displacement Landscape
Raghuram Tattamangalam Raman, Jeffin Shibu, Revathy Padmanabhan +1
We propose an energy-based framework to analyze the statics and dynamics of a ferroelectric negative capacitance-hybrid Microelectromechanical System (MEMS) actuator. A mapping fun…
Kramers' escape problem for white noise driven switching in ferroelectrics
Madhav Ramesh, Amit Verma, Arvind Ajoy
A simulation-based study of stochastic resonance (SR) in a ferroelectric capacitor is presented. The SR phenomenon involves the detection of weak signals by adding an optimal amoun…
Analysis of Electrostatic MEMS Using Energy-Charge Landscape
Raghuram Tattamangalam Raman, Arvind Ajoy, Revathy Padmanabhan
A common way to analyze electrostatic microelectromechanical systems (MEMS) actuators is to use their energy-displacement landscape. Here, we describe an alternative approach to an…
Dynamics of Ferroelectric Negative Capacitance -- Electrostatic MEMS Hybrid Actuators
Raghuram TR, Arvind Ajoy
We propose a framework to model ferroelectric negative capacitance: electrostatic Micro Electro Mechanical Systems (MEMS) hybrid actuators and analyze their dynamic (step input) re…
Multiscale model for phonon-assisted band-to-band tunneling in semiconductors
Arvind Ajoy, S. E. Laux, Kota V. R. M. Murali +1
We present a TCAD compatible multiscale model of phonon-assisted band-to-band tunneling (BTBT) in semiconductors, that incorporates the non-parabolic nature of complex bands within…
Brillouin zone unfolding of Complex Bands in a nearest neighbour Tight Binding scheme
Arvind Ajoy, Kota V R M Murali, Shreepad Karmalkar
Complex bands in a semiconductor crystal, along a general direction , can be computed by casting Schrödinger's equation as a generalized polynomial ei…
Brillouin zone unfolding method for effective phonon spectra
Timothy B. Boykin, Arvind Ajoy, Hesameddin Ilatikhameneh +2
Thermal properties are of great interest in modern electronic devices and nanostructures. Calculating these properties is straightforward when the device is made from a pure materi…
