Direct imaging of band profile in single layer MoS2 on graphite: quasiparticle energy gap, metallic edge states, and edge band bending.
Using scanning tunneling microscopy and spectroscopy, the electronic structures of single layer MoS2 on graphite are probed and an exciton binding energy value is deduced that is lower than current theoretical predictions. Expand
Formation of Atomically Flat Silver Films on GaAs with a "Silver Mean" Quasi Periodicity
A flat epitaxial silver film on a gallium arsenide [GaAs(110)] surface was synthesized in a two-step process. Deposition of a critical thickness of silver at low temperature led to the formation of aExpand
Persistent superconductivity in ultrathin Pb films: a scanning tunneling spectroscopy study.
This work probed the superconducting energy gap of epitaxially grown Pb films as a function of the layer thickness in an ultrathin regime and found that the Tc oscillation correlates directly with the density of states oscillation at E(F) . Expand
Observation of topological surface state quantum Hall effect in an intrinsic three-dimensional topological insulator
Experimentalists have observed the predicted half-integer quantum Hall effect using the topological insulator BiSbTeSe2, which exhibits topological surface states at room temperature, with eachExpand
Resonance fluorescence from a coherently driven semiconductor quantum dot in a cavity.
It is shown that resonance fluorescence, i.e., the resonant emission of a coherently driven two-level system, can be realized with a semiconductor quantum dot and second-order correlation measurements further confirm nonclassical light emission. Expand
Plasmonic Nanolaser Using Epitaxially Grown Silver Film
The low-threshold, continuous-wave operation of a subdiffraction nanolaser based on surface plasmon amplification by stimulated emission of radiation is reported on, opening a scalable platform for low-loss, active nanoplasmonics. Expand
``Electronic Growth'' of Metallic Overlayers on Semiconductor Substrates
We present a novel {open_quotes}electronic growth{close_quotes} model for metallic thin films on semiconductor substrates. Depending on the competition between the effects of quantum confinement,Expand
Probing Critical Point Energies of Transition Metal Dichalcogenides: Surprising Indirect Gap of Single Layer WSe2.
Detailed quasi-particle electronic structures in transition metal dichalcogenides are revealed, including the quasi- particle gaps, critical point energy locations, and their origins in the Brillouin zones by using a comprehensive form of scanning tunneling spectroscopy. Expand
Plasmonic nanolaser using epitaxially grown silver film
Successful development of epitaxial Ag as a new plasmonic platform has enabled low-threshold, continuous-wave (CW) operation of a SPASER-enabled nanolaser comprised of a subdiffraction plasmonicExpand
Observation of Coulomb repulsion between Cu intercalants in CuxBi2Se3
Using scanning tunneling microscopy and ab initio simulations, we have identified several configurations for Cu dopants in ${\text{Cu}}_{x}$${\text{Bi}}_{2}$${\text{Se}}_{3}$, with Cu intercalantsExpand
