Fokker--Planck framework for stochastic octupole moment dynamics in chiral antiferromagnet Mn3Sn
Siyuan Qian, Shaloo Rakheja
We develop a reduced stochastic framework for thermally assisted octupole moment dynamics in Mn3Sn by combining the reduced Landau--Lifshitz--Gilbert (LLG) equation with the Fokker…
Hot LO Phonon-Induced RF Nonlinearity in GaN High-Electron-Mobility Transistors
Ankan Ghosh Dastider, Matt Grupen, Nicholas C. Miller +1
Hot longitudinal optical (LO) phonons in GaN have recently been identified as a major factor degrading the DC performance of GaN high-electron-mobility transistors (HEMTs) by 30-60…
Physics-based Full-band GaN High-Electron-Mobility Transistor Simulation Suggests Upper Bound of LO Phonon Lifetime
Ankan Ghosh Dastider, Matt Grupen, Ashwin Tunga +1
Intrinsic limits to device performance arise from fundamental material properties that define the best achievable operation, independent of engineering constraints. In GaN high-ele…
Enhancing Hole Mobility in Monolayer p-FETs via Process-Induced Compression
He Lin Zhao, Sheikh Mohd Ta-Seen Afrid, Dongyoung Yoon +7
Understanding the interactions between strain, interfacial mechanics, and electrical performance is critical for designing beyond silicon electronics based on hetero-integrated 2D…
Strain-tunable inter-valley scattering defines universal mobility enhancement in n- and p-type 2D TMDs
Sheikh Mohd Ta-Seen Afrid, He Lin Zhao, Arend M. van der Zande +1
Strain fundamentally alters carrier transport in semiconductors by modifying their band structure and scattering pathways. In transition-metal dichalcogenides (TMDs), an emerging c…
Influence of thermal noise on the field-driven dynamics of the non-collinear antiferromagnet Mn3Sn
Siyuan Qian, Ankit Shukla, Shaloo Rakheja
experiences a tensile strain when grown epitaxially on , and thus the energy landscape changes from six-…
