Advances and opportunities for automated robotic preparation of 2D materials and fabrication of 2D heterostructures
S. Davari, D. L. Duong, T. Faltermeier +7
The mechanical exfoliation, transfer, and stacking of 2D atomic sheets from van der Waals crystals synergize to enable atomic layer-by-atomic layer engineering of 2D heterostructur…
Coupling Between Magnetic and Transport Properties in Magnetic Layered Material Mn2-xZnxSb
Md Rafique Un Nabi, Rabindra Basnet, Krishna Pandey +9
We synthesized single crystals for Mn2-xZnxSb and studied their magnetic and electronic transport properties. This material system displays rich magnetic phase tunable with tempera…
Iconary: A Pictionary-Based Game for Testing Multimodal Communication with Drawings and Text
Christopher Clark, Jordi Salvador, Dustin Schwenk +13
Communicating with humans is challenging for AIs because it requires a shared understanding of the world, complex semantics (e.g., metaphors or analogies), and at times multi-modal…
Integration of multi-layer black phosphorus into photoconductive antennas for THz emission
M. H. Doha, J. I. Santos Batista, A. F. Rawwagah +6
We report the fabrication, characterization, and modeling of photoconductive antennas using 40 nm thin-film flakes of black phosphorus (BP) as the photoconductor and hexagonal boro…

Fatemeh Barati, Josh P. Thompson, Matthieu C. Dartiailh +8
The transparent interface in epitaxial Al-InAs heterostructures provides an excellent platform for potential advances in mesoscopic and topological superconductivity. Semiconductor…
Gate-defined, Accumulation-mode Quantum Dots in Monolayer and Bilayer WSe
S. Davari, J. Stacy, A. M. Mercado +7
We report the fabrication and characterization of gate-defined hole quantum dots in monolayer and bilayer WSe. The devices were operated with gates above and below the WSe…
Evidence for a magnetic-field induced ideal type-II Weyl state in antiferromagnetic topological insulator Mn(Bi1-xSbx)2Te4
Seng Huat Lee, David Graf, Yanglin Zhu +18
The discovery of Weyl semimetals (WSMs) has fueled tremendous interest in condensed matter physics. WSMs require breaking of either inversion symmetry (IS) or time-reversal symmetr…
Growth and Strain Engineering of Trigonal Te for Topological Quantum Phases in Non-Symmorphic Chiral Crystals
Rabindra Basnet, M. Hasan Doha, Takayuki Hironaka +5
Strained trigonal Te has been predicted to host Weyl nodes supported by a non-symmorphic chiral symmetry. Using low-pressure physical vapor deposition, we systematically explored t…
Exfoliation energy, quasi-particle bandstructure, and excitonic properties of selenium and tellurium atomic chains
Eesha Andharia, Thaneshwor P. Kaloni, Gregory J. Salamo +3
Effects that are not captured by the generalized-gradient density-functional theory play a prominent effect on the structural binding, and on the electronic and optical properties…
Two-dimensional disorder in black phosphorus and monochalcogenide monolayers
