Atomic and Electronic Structure of Strongly Charged Domain Walls in van der Waals α-InSe
Gillian Nolan, Edmund Han, Shahriar Muhammad Nahid +4
Here, we use atomic resolution scanning transmission electron microscopy (STEM) and first principles calculations to study the atomic and electronic structure of strongly charged d…
Ultra-tuning of nonlinear drumhead MEMS resonators by electro-thermoelastic buckling
Ali Kanj, Paolo F. Ferrari, Arend M. van der Zande +2
Nonlinear micro-electro-mechanical systems (MEMS) resonators open new opportunities in sensing and signal manipulation compared to their linear counterparts by enabling frequency t…
Structural phase transition and material properties of few-layer monochalcogenides
Mehrshad Mehboudi, Benjamin M. Fregoso, Yurong Yang +6
GeSe and SnSe monochalcogenide monolayers and bilayers undergo a two-dimensional phase transition from a rectangular unit cell to a square unit cell at a temperature well bel…
Two-dimensional disorder in black phosphorus and monochalcogenide monolayers
Mehrshad Mehboudi, Alex M. Dorio, Wenjuan Zhu +6
Ridged, orthorhombic two-dimensional atomic crystals with a bulk {\em Pnma} structure such as black phosphorus and monochalcogenide monolayers are an exciting and novel material pl…
Valley Splitting and Polarization by the Zeeman Effect in Monolayer MoSe2
Yilei Li, Jonathan Ludwig, Tony Low +12
We have measured circularly polarized photoluminescence in monolayer MoSe2 under perpendicular magnetic fields up to 10 T. At low doping densities, the neutral and charged excitons…
Atomically thin p-n junctions with van der Waals heterointerfaces
Chul-Ho Lee, Gwan-Hyoung Lee, Arend M. van der Zande +10
Semiconductor p-n junctions are essential building blocks for modern electronics and optoelectronics. In conventional semiconductors, a p-n junction produces depletion regions of f…
Controlling the Spontaneous Emission Rate of Monolayer MoS in a Photonic Crystal Nanocavity
Xuetao Gan, Yuanda Gao, Kin Fai Mak +8
We report on controlling the spontaneous emission (SE) rate of a molybdenum disulfide (MoS) monolayer coupled with a planar photonic crystal (PPC) nanocavity. Spatially resolve…
Graphene Metallization of High-Stress Silicon Nitride Resonators for Electrical Integration
Sunwoo Lee, Vivekananda P. Adiga, Robert A. Barton +7
High stress stoichiometric silicon nitride resonators, whose quality factors exceed one million, have shown promise for applications in sensing and signal processing. Yet, electric…
Grains and grain boundaries in highly crystalline monolayer molybdenum disulfide
Arend M. van der Zande, Pinshane Y. Huang, Daniel A. Chenet +7
Recent progress in large-area synthesis of monolayer molybdenum disulfide, a new two-dimensional direct-bandgap semiconductor, is paving the way for applications in atomically thin…
Graphene growth on h-BN by Molecular Beam Epitaxy
Jorge M. Garcia, Ulrich Wurstbauer, Antonio Levy +10
The growth of single layer graphene nanometer size domains by solid carbon source molecular beam epitaxy on hexagonal boron nitride (h-BN) flakes is demonstrated. Formation of sing…
Entropic Spectral Broadening in Carbon Nanotube Resonators
Arthur W. Barnard, Vera Sazonova, Arend M. van der Zande +1
We simulated the behavior of suspended carbon-nanotube (CNT) resonators over a broad range of temperatures to address the unexplained spectral broadening and frequency shifts seen…
Imaging Grains and Grain Boundaries in Single-Layer Graphene: An Atomic Patchwork Quilt
Pinshane Y. Huang, Carlos S. Ruiz-Vargas, Arend M. van der Zande +8
The properties of polycrystalline materials are often dominated by the size of their grains and by the atomic structure of their grain boundaries. These effects should be especiall…
Photo-Thermoelectric Effect at a Graphene Interface Junction
Xiaodong Xu, Nathaniel M. Gabor, Jonathan S. Alden +2
We investigate the optoelectronic response of a graphene interface junction, formed with bilayer and single-layer graphene, by photocurrent (PC) microscopy. We measure the polarity…
