Crossover in dynamics in the Kob-Andersen binary mixture glass-forming liquid
Pallai Das, Srikanth Sastry
Glass-forming liquids are broadly classified as being fragile or strong, depending on the deviation from Arrhenius behavior of their relaxation times. A fragile to strong crossover…
Design and analysis of electro-optic modulators based on high contrast gratings (HCGs) in AlGaN/GaN heterostructures
Pallabi Das, Shlok Vaibhav Singh, Siddharth Tallur
Recently High Electron Mobility Transistor (HEMT) inspired III-V electro-optic modulator topologies were proposed for realizing high speed electro-optic modulators leveraging plasm…
Large Piezoelectric-Polymer Composites For RF Acoustic Resonators
Pallabi Das, Siddharth Tallur
While piezoelectric transduction enables designing acoustic resonators operating at multi-GHz frequencies, the deposition of piezoelectric materials typically requires high tempera…
Design and analysis of high electron mobility transistor (HEMT) inspired III-V electro-optic modulator topologies
Pallabi Das, Tian-Li Wu, Siddharth Tallur
III-V heterostructure based high electron mobility transistors (HEMTs) offer superior performance as compared to CMOS silicon transistors owing to the high mobility in the 2D elect…
