Enhanced Permittivity in Wurtzite ScAlN through Nanoscale Sc Clustering
James L Hart, Andrew C Lang, Matthew T Hardy +8
ScN alloyed AlN (ScxAl1-xN, ScAlN) is a wurtzite semiconductor with attractive ferroelectric, dielectric, piezoelectric, and optical properties. Here, we show that ScAlN films (wit…
A comprehensive equivalent circuit model for high overtone bulk acoustic resonators (HBARs)
Vikrant J. Gokhale, Brian P. Downey
This paper presents a new and comprehensive equivalent circuit model for high overtone bulk acoustic resonators (HBARs). HBARs demonstrate several very sharp resonance modes distri…
Modeling Practical Capacitive Structures for Electronic and Dielectric Property Extraction and Analysis
James G. Champlain, Vikrant J. Gokhale, Matthew T. Hardy +1
A method for modeling the full steady-state and small-signal behavior of practical capacitive structures, such as metal-insulator-metal capacitors, diodes, and transistors, is pres…
Strongly dispersive dielectric properties of high-ScN-fraction ScAlN deposited by molecular beam epitaxy
Vikrant J. Gokhale, James G. Champlain, Matthew T. Hardy +9
We present a comprehensive study of dielectric properties including complex permittivity, loss, and leakage of high-ScN-fraction ScAlN thin films grown using molecular beam epitaxy…
Direct visualization of electromagnetic wave dynamics by laser-free ultrafast electron microscopy
Xuewen Fu, Erdong Wang, Yubin Zhao +7
Integrating femtosecond (fs) lasers to electron microscopies has enabled direct imaging of transient structures and morphologies of materials in real time and space, namely, ultraf…
Epitaxial bulk acoustic wave resonators as highly coherent multi-phonon sources for quantum acoustodynamics
Vikrant J. Gokhale, Brian P. Downey, D. Scott Katzer +4
Solid-state quantum acoustodynamic (QAD) systems provide a compact platform for quantum information storage and processing by coupling acoustic phonon sources with superconducting…
