Endotaxial Stabilization of 2D Charge Density Waves with Long-range Order
Suk Hyun Sung, Nishkarsh Agarwal, Ismail El Baggari +10
Charge density waves are emergent quantum states that spontaneously reduce crystal symmetry, drive metal-insulator transitions, and precede superconductivity. In low-dimensions, di…
Magnon-magnon interactions induced by spin pumping-driven symmetry breaking in synthetic antiferromagnets
Mitra Mani Subedi, Kuangyin Deng, Yuzan Xiong +9
The richness in both the dispersion and energy of antiferromagnetic magnons has spurred the magnetism community to consider antiferromagnets for future spintronic/magnonic applicat…
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…
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…
Perspective: Towards the predictive discovery of ambipolarly dopable ultra-wide-band-gap semiconductors: the case of rutile GeO
S. Chae, K. A. Mengle, K. Bushick +8
Ultrawide-band-gap (UWBG) semiconductors are promising for fast, compact, and energy-efficient power-electronics devices. Their wider band gaps result in higher breakdown electric…
Two-dimensional charge order stabilized in clean polytype heterostructures
Suk Hyun Sung, Noah Schnitzer, Steve Novakov +15
Compelling evidence suggests distinct correlated electron behavior may exist only in clean 2D materials such as 1T-TaS2. Unfortunately, experiment and theory suggest that extrinsic…
A Narrowband Spintronic Terahertz Emitter based on Magnetoelastic Heterostructures
Shihao Zhuang, Peter B. Meisenheimer, John T. Heron +1
Narrowband terahertz (THz) radiation is crucial for high-resolution spectral identification, but a narrowband THz source driven by femtosecond (fs) laser has remained scarce. Here,…
Boron Arsenide Heterostructures: Lattice-Matched Heterointerfaces, and Strain Effects on Band Alignments and Mobility
Kyle Bushick, Sieun Chae, Zihao Deng +2
BAs is III-V semiconductor with ultra-high thermal conductivity, but many of its electronic properties are unknown. This work applies predictive atomistic calculations to investiga…
Imaging uncompensated moments and exchange-biased emergent ferromagnetism in FeRh thin films
Isaiah Gray, Gregory M. Stiehl, John T. Heron +5
Uncompensated moments in antiferromagnets are responsible for exchange bias in antiferromagnet/ferromagnet heterostructures; however, they are difficult to directly detect because…
Rutile GeO2: an ultrawide-band-gap semiconductor with ambipolar doping
Sieun Chae, Jihang Lee, Kelsey A. Mengle +2
Ultra-wide-band-gap (UWBG) semiconductors have tremendous potential to advance electronic devices as device performance improves superlinearly with increasing gap. Ambipolar doping…
Spin Seebeck imaging of spin-torque switching in antiferromagnetic Pt/NiO heterostructures
Isaiah Gray, Takahiro Moriyama, Nikhil Sivadas +10
As electrical control of Néel order opens the door to reliable antiferromagnetic spintronic devices, understanding the microscopic mechanisms of antiferromagnetic switching is cruc…
Point defects and dopants of boron arsenide from first-principles calculations: donor compensation and doping asymmetry
Sieun Chae, Kelsey Mengle, John T. Heron +1
We apply hybrid density functional theory calculations to identify the formation energies and thermodynamic charge transition levels of native point defects, common impurities, and…
Unexpected Termination Switching and Polarity Compensation in LaAlO3/SrTiO3 heterostructures
