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…
Atomically smooth films of CsSb: a chemically robust visible light photocathode
C. T. Parzyck, C. A. Pennington, W. J. I. DeBenedetti +14
Alkali antimonide semiconductor photocathodes provide a promising platform for the generation of high brightness electron beams, which are necessary for the development of cutting-…
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…
Antiferromagnetic metal phase in an electron-doped rare-earth nickelate
Qi Song, Spencer Doyle, Grace A. Pan +28
Long viewed as passive elements, antiferromagnetic materials have emerged as promising candidates for spintronic devices due to their insensitivity to external fields and potential…
Electronic band structure of a superconducting nickelate probed by the Seebeck coefficient in the disordered limit
G. Grissonnanche, G. A. Pan, H. LaBollita +9
Superconducting nickelates are a new family of strongly correlated electron materials with a phase diagram closely resembling that of superconducting cuprates. While analogy with t…
Superconductivity in a quintuple-layer square-planar nickelate
Grace A. Pan, Dan Ferenc Segedin, Harrison LaBollita +18
Since the discovery of high-temperature superconductivity in the copper oxide materials, there have been sustained efforts to both understand the origins of this phase and discover…
Instabilities of heavy magnons in an anisotropic magnet
Xiaojian Bai, Shang-Shun Zhang, Hao Zhang +5
The search for new elementary particles is one of the most basic pursuits in physics, spanning from subatomic physics to quantum materials. Magnons are the ubiquitous elementary qu…
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…
Observation of 4- and 6-magnon bound-states in the spin-anisotropic frustrated antiferromagnet FeI
Anaëlle Legros, Shang-Shun Zhang, Xiaojian Bai +6
Spin-waves e.g. magnons are the conventional elementary excitations of ordered magnets. However, other possibilities exist. For instance, magnon bound-states can arise due to attra…
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…
Strain-stabilized superconductivity
Jacob P. Ruf, Hanjong Paik, Nathaniel J. Schreiber +12
Superconductivity is among the most fascinating and well-studied quantum states of matter. Despite over 100 years of research, a detailed understanding of how features of the norma…
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…
