Collective scattering from quantum dots in a photonic crystal waveguide

Joel Q. Grim, Ian Welland, Samuel G. Carter +7

We demonstrate scattering of laser light from two InAs quantum dots coupled to a photonic crystal waveguide, which is achieved by strain-tuning the optical transitions of the dots…

Enabling remote quantum emission in 2D semiconductors via porous metallic networks

Jose J. Fonseca, Andrew L. Yeats, Brandon Blue +11

The interaction between two-dimensional crystals (2DCs) and metals is ubiquitous in 2D material research. Here we report how 2DC overlayers influence the recrystallization of relat…

Helicity dependent photocurrent in electrically gated (Bi,Sb)_2Te_3 thin films

Yu Pan, Qing-Ze Wang, Andrew L. Yeats +7

Circularly polarized photons are known to generate a directional helicity-dependent photocurrent in three-dimensional topological insulators at room temperature. Surprisingly, the…

Optical charge state control of spin defects in 4H-SiC

Gary Wolfowicz, Christopher P. Anderson, Andrew L. Yeats +5

Defects in silicon carbide (SiC) have emerged as a favorable platform for optically-active spin-based quantum technologies. Spin qubits exist in specific charge states of these def…

Local optical control of ferromagnetism and chemical potential in a topological insulator

Andrew L. Yeats, Peter J. Mintun, Yu Pan +4

Many proposed experiments involving topological insulators (TIs) require spatial control over time-reversal symmetry and chemical potential. We demonstrate reconfigurable micron-sc…

Persistent Optical Gating of a Topological Insulator

Andrew L. Yeats, Yu Pan, Anthony Richardella +3

Topological insulators (TIs) have attracted much attention due to their spin-polarized surface and edge states, whose origin in symmetry gives them intriguing quantum-mechanical pr…

Interplay between ferromagnetism, surface states, and quantum corrections in a magnetically doped topological insulator

Duming Zhang, Anthony Richardella, David W. Rench +12

The breaking of time-reversal symmetry by ferromagnetism is predicted to yield profound changes to the electronic surface states of a topological insulator. Here, we report on a co…

Coherent Heteroepitaxy of Bi2Se3 on GaAs (111)B

A. Richardella, D. M. Zhang, J. S. Lee +6

We report the heteroepitaxy of single crystal thin films of Bi2Se3 on the (111)B surface of GaAs by molecular beam epitaxy. We find that Bi2Se3 grows highly c-axis oriented, with a…
