Tuning of Fermi Contour Anisotropy in GaAs (001) 2D Holes via Strain
Insun Jo, M. A. Mueed, L. N. Pfeiffer +5
We demonstrate tuning of the Fermi contour anisotropy of two-dimensional (2D) holes in a symmetric GaAs (001) quantum well via the application of in-plane strain. The ballistic tra…
Transference of Fermi Contour Anisotropy to Composite Fermions
Insun Jo, K. A. Villegas Rosales, M. A. Mueed +6
There has been a surge of recent interest in the role of anisotropy in interaction-induced phenomena in two-dimensional (2D) charged carrier systems. A fundamental question is how…
A nearly relaxation-free opto-electronic memory from ultra-thin graphene-MoS binary hybrids
Kallol Roy, Medini Padmanabhan, Srijit Goswami +4
Ultra-thin planar heterostructures of graphene and other two-dimensional crystals have recently attracted much interest. Very high carrier mobility in a graphene-on-boron nitride a…
Electrochemical integration of graphene with light absorbing copper-based thin films
Medini Padmanabhan, Kallol Roy, Gopalakrishnan Ramalingam +2
We present an electrochemical route for the integration of graphene with light sensitive copper-based alloys used in optoelectronic applications. Graphene grown using chemical vapo…
Effective Mass and Spin Susceptibility of Dilute Two-Dimensional Holes in GaAs
YenTing Chiu, Medini Padmanabhan, T. Gokmen +4
We report effective hole mass () measurements through analyzing the temperature dependence of Shubnikov-de Haas oscillations in dilute (density cm$…
Transference of Transport Anisotropy to Composite Fermions
T. Gokmen, Medini Padmanabhan, M. Shayegan
When interacting two-dimensional electrons are placed in a large perpendicular magnetic field, to minimize their energy, they capture an even number of flux quanta and create new p…
