3D Atomic-Scale Metrology of Strain Relaxation and Roughness in Gate-All-Around (GAA) Transistors via Electron Ptychography
Shake Karapetyan, Steven E. Zeltmann, Glen Wilk +3
To improve transistor density and electronic performance, next-generation semiconductor devices are adopting three-dimensional architectures and feature sizes down to the few-nm re…
PtyRAD: A High-performance and Flexible Ptychographic Reconstruction Framework with Automatic Differentiation
Chia-Hao Lee, Steven E. Zeltmann, Dasol Yoon +2
Electron ptychography has recently achieved unprecedented resolution, offering valuable insights across diverse material systems, including in three dimensions. However, high-quali…
Molecular Beam Epitaxy of KTaO
Tobias Schwaigert, Salva Salmani-Razaie, Matthew R. Barone +6
Strain-engineering is a powerful means to tune the polar, structural, and electronic instabilities of incipient ferroelectrics. KTaO3 is near a polar instability and shows anisotro…
Momentum-resolved electronic band structure and offsets in an epitaxial NbN/GaN superconductor/semiconductor heterojunction
Tianlun Yu, John Wright, Guru Khalsa +9
The electronic structure of heterointerfaces play a pivotal role in their device functionality. Recently, highly crystalline ultrathin films of superconducting NbN have been integr…
Adsorption-Controlled Growth of Ga2O3 by Suboxide Molecular-Beam Epitaxy
Patrick Vogt, Felix V. E. Hensling, Kathy Azizie +15
This paper introduces a growth method---suboxide molecular-beam epitaxy (S-MBE)---which enables the growth of Ga2O3 and related materials at growth rates exceeding 1 micrometer per…
Direct Visualization of Trimerized States in 1T'-TaTe
Ismail El Baggari, Nikhil Sivadas, Gregory M. Stiehl +4
Transition-metal dichalcogenides containing tellurium anions show remarkable charge-lattice modulated structures and prominent interlayer character. Using cryogenic scanning transm…
Unraveling the role of V-V dimer on the vibrational properties of VO by first-principles simulations and Raman spectroscopic analysis
Wasim Raja Mondal, Egor Evlyukhin, Sebastian A. Howard +5
We investigate the vibrational properties of VO2, particularly the low temperature M1 phase by first-principles calculations using the density functional theory as well as Raman sp…
Control of polymorphism during epitaxial growth of hyperferroelectric candidate LiZnSb on GaSb (111)B
Dongxue Du, Patrick J. Strohbeen, Hanjong Paik +6
A major challenge for ferroelectric devices is the depolarization field, which competes with and often destroys long-range polar order in the limit of ultrathin films. Recent theor…
Single crystal growth and characterization of BaScNbO -- a novel substrate for BaSnO films
C. Guguschev, D. Klimm, M. Brützam +6
Large single crystals of the double-perovskite BaScNbO were grown from the melt for the first time. With a lattice parameter at room temperature of 4.11672(1) Å, this cubic…
Exceptionally high, strongly temperature dependent, spin Hall conductivity of SrRuO3
Yongxi Ou, Zhe Wang, Celesta S. Chang +7
Spin-orbit torques (SOT) in thin film heterostructures originate from strong spin-orbit interactions (SOI) that, in the bulk, generate a spin current as the result of extrinsic spi…
Engineering Dzyaloshinskii-Moriya interaction in B20 thin film chiral magnets
Emrah Turgut, Hanjong Paik, Kayla Nguyen +3
Chiral magnetic MnFeGe compounds have an antisymmetric exchange interaction that is tunable with the manganese stoichiometric fraction, . Although millimeter-scale,…
