Ten-Second Electron-Spin Coherence in Isotopically Engineered Diamond
Takashi Yamamoto, H. Benjamin van Ommen, Kai-Niklas Schymik +7
Solid-state spin defects are a promising platform for quantum networks. A key requirement is to combine long ground-state spin-coherence times with a coherent optical transition fo…
Mechanical Reinforcement of Graphene via Wrinkling
Hadi Arjmandi-Tash, Roshan Prasad, Hanqing Liu +3
Mechanical cantilevers are central to nanotechnology, with ultimate sensitivity achieved at the atomic limit, where low bending rigidity makes stability the fundamental challenge.…
Symmetry-breaking induced frequency combs in graphene resonators
Ata Keşkekler, Hadi Arjmandi, Peter G. Steeneken +1
Nonlinearities are inherent to the dynamics of two-dimensional materials. Phenomena like intermodal coupling already arise at amplitudes of only a few nanometers, and a range of un…
Electromagnetic Absorption as a Novel Tool in Chemical Vapor Deposition Toolbox: Ultra-Fast Growth of Continuous Graphene Film
Hadi Arjmandi-Tash, Gregory F. Schneider
This report introduces the electromagnetic absorption of the catalyst as a novel knob in optimizing chemical vapor deposition of graphene. A chromium film initially deposited at on…
Topological Regard to Graphene: Elucidating the Morphology-Strain Correlation
Hadi Arjmandi-Tash, Alexander Kloosterman, Gregory F. Schneider
Graphene, dubbed as a two-dimensional material represents the topological concept of "surface" embedded in a three-dimensional space. This regard enables to employ existing theorie…
A zero-depth nanopore capillary for the analysis of translocating biomolecules
Hadi Arjmandi-Tash, Amedeo Bellunato, Chenyu Wen +4
High-fidelity analysis of translocating biomolecules through nanopores demands shortening the nanocapillary length to a minimal value. Existing nanopores and capillaries, however,…
Biaxial compression of centimeter scale graphene on strictly 2D substrate
Hadi Arjmandi-Tash, Hessam Sokooti, Jiang Lin +3
Biaxial compression of centimetre-scale graphene, freely standing on the surface of water is studied. Within this platform, we report full stress-strain compression of graphene ide…
High-Yield Proximity-Induced Chemical Vapor Deposition of Graphene Over Millimeter-Sized Hexagonal Boron Nitride
Hadi Arjmandi-Tash, Dipankar Kalita, Zheng Han +9
We present a transfer-free preparation method for graphene on hexagonal boron nitride (h-BN) crystals by chemical vapor deposition of graphene via a catalytic proximity effect, i.e…
Hybrid cold and hot-wall chamber for fast synthesis of uniform graphene
Hadi Arjmandi-Tash, Nikita Lebedev, Pauline van Deursen +2
We introduce a novel modality in the CVD growth of graphene which combines the cold-wall and hot-wall reaction chambers. This hybrid mode preserves the advantages of a cold-wall ch…
Rupture index: a quantitative measurement of sub-micrometer cracks in graphene
Hadi Arjmandi-Tash, Lin Jiang, Grégory F. Schneider
Per weight graphene is stronger than steel, but because graphene is so thin, it breaks and evidently forms cracks during handling, particularly when supporting polymers are not use…
In-Situ Growth of Graphene on Hexagonal Boron Nitride for Electronic Transport Applications
Hadi Arjmandi-Tash
Transferring graphene flakes onto hexagonal boron nitride (h-BN) has been the most popular approach for the fabrication of graphne/h-BN heterostructures so far. The orientation bet…
Collapse of superconductivity in a hybrid tin-graphene Josephson junction array
Zheng Han, Adrien Allain, Hadi Arjmandi-Tash +4
When a Josephson junction array is built with hybrid superconductor/metal/superconductor junctions, a quantum phase transition from a superconducting to a two-dimensional (2D) meta…
Suppression of Multilayer Graphene Patches during CVD Graphene growth on Copper
Zheng Han, Amina Kimouche, Adrien Allain +7
By limiting the carbon segregation at the copper surface defects, a pulsed chemical vapor deposition method for single layer graphene growth is shown to inhibit the formation of fe…
