Orbitals of Artificial Atoms in a Gapped Two-Dimensional Vacuum
Mong-Wen Gu, Aizhan Sabitova, Taner Esat +4
Advances in nanotechnology now allow the creation of artificial atoms - engineered structures whose electronic states closely mimic those of real atoms. Understanding how these art…
Low-Field Metal-Insulator Transition in AB-Stacked Bilayer Graphene
Amarnath Chakraborty, Aleksandr Rodin, Shaffique Adam +1
We investigate the interplay of in-plane magnetic and transverse electric fields in AB-stacked bilayer graphene. In prior work neglecting trigonal warping, we demonstrated that thi…
Tunneling Plasmonics in Bilayer Graphene
Z. Fei, E. G. Iwinski, G. X. Ni +14
We report experimental signatures of plasmonic effects due to electron tunneling between adjacent graphene layers. At sub-nanometer separation, such layers can form either a strong…
Valleytronics in Tin (II) Sulfide
A. S. Rodin, L. C. Gomes, A. Carvalho +1
Tin (II) sulfide (SnS) is a layered mineral found in nature. In this paper, we study the two-dimensional form of this material using a combination of \emph{ab initio} calculation a…
Infrared nano-spectroscopy and imaging of collective superfluid excitations in conventional and high-temperature superconductors
H. T. Stinson, J. S. Wu, B. Y. Jiang +8
We investigate near-field infrared spectroscopy and superfluid polariton imaging experiments on conventional and unconventional superconductors. Our modeling shows that near-field…
Electronic and plasmonic phenomena at graphene grain boundaries
Z. Fei, A. S. Rodin, W. Gannett +13
Graphene, a two-dimensional honeycomb lattice of carbon atoms, is of great interest in (opto)electronics and plasmonics and can be obtained by means of diverse fabrication techniqu…
Plasmonic Hot Spots in Triangular Tapered Graphene Microcrystals
A. S. Rodin, Z. Fei, A. S. McLeod +4
Recently, plasmons in graphene have been observed experimentally using scattering scanning near-field optical microscopy. In this paper, we develop a simplified analytical approach…
Excitonic Collapse in Semiconducting Transition Metal Dichalcogenides
A. S. Rodin, A. H. Castro Neto
Semiconducting transition metal dichalcogenides (STMDC) are two-dimensional (2D) crystals characterized by electron volt size band gaps, spin-orbit coupling (SOC), and d-orbital ch…
Gate-tuning of graphene plasmons revealed by infrared nano-imaging
Z. Fei, A. S. Rodin, G. O. Andreev +12
Surface plasmons are collective oscillations of electrons in metals or semiconductors enabling confinement and control of electromagnetic energy at subwavelength scales. Rapid prog…
