Width-dependent Photoluminescence and Anisotropic Raman Spectroscopy from Monolayer MoS Nanoribbons
Guohua Wei, Erik J. Lenferink, David A. Czaplewski +1
Single layers of transition metal dichalcogenides such as MoS are direct bandgap semiconductors with optical and electronic properties distinct from multilayers due to strong v…
Enhanced Conductivity Along Lateral Homojunction Interfaces of Atomically Thin Semiconductors
Ying Jia, Teodor K. Stanev, Erik J. Lenferink +1
Energy band realignment at the interfaces between materials in heterostructures can give rise to unique electronic characteristics and non-trivial low-dimensional charge states. In…
Valley Polarization in Size-Tunable Monolayer Semiconductor Quantum Dots
Guohua Wei, David A. Czaplewski, Erik J. Lenferink +3
Three-dimensional confinement allows semiconductor quantum dots (QDs) to exhibit size-tunable electronic and optical properties that enable a wide range of opto-electronic applicat…
Evaluation of defects in cuprous oxide through exciton luminescence imaging
Laszlo Frazer, Erik J. Lenferink, Kelvin B. Chang +3
The various decay mechanisms of excitons in cuprous oxide (Cu2O) are highly sensitive to defects which can relax selection rules. Here we report cryogenic hyperspectral imaging of…
Coherent optical non-reciprocity in axisymmetric resonators
Erik J. Lenferink, Guohua Wei, Nathaniel P. Stern
We describe an approach to optical non-reciprocity that exploits the local helicity of evanescent electric fields in axisymmetric resonators. By interfacing an optical cavity to he…
Low-Temperature Magnetization Dynamics of Magnetic Molecular Solids in a Swept Field
Erik Lenferink, Avinash Vijayaraghavan, Anupam Garg
The swept-field experiments on magnetic molecular solids such as \Fe8 are studied using Monte Carlo simulations. A kinetic equation is developed to understand the phenomenon. It is…
