Resonant and Time-Resolved Spin Noise Spectroscopy
Brennan C. Pursley, Xinlin Song, Vanessa Sih
We demonstrate a method to extend the range of pulsed laser spin noise measurements to long spin lifetimes. We use an analog time-domain detection scheme with a bandwidth limited o…
Robustness of n-GaAs Carrier Spin Properties to 5 MeV Proton Irradiation
Brennan C. Pursley, Xinlin Song, R. O. Torres-Isea +3
Modern electronic devices utilize charge to transmit and store information. This leaves the information susceptible to external influences, such as radiation, that can introduce sh…
Ferromagnetism and infrared electrodynamics of GaMnAs}
B. C. Chapler, S. Mack, R. C. Myers +7
We report on the magnetic and the electronic properties of the prototype dilute magnetic semiconductor GaMnAs using infrared (IR) spectroscopy. Trends in the ferromagne…
Spin lifetime measurements in GaAsBi thin films
Brennan Pursley, M. Luengo-Kovac, G. Vardar +2
Photoluminescence spectroscopy and Hanle effect measurements are used to investigate carrier spin dephasing and recombination times in the semiconductor alloy GaAsBi as a function…
An infrared probe of the insulator-to-metal transition in GaMnAs and GaBeAs
B. C. Chapler, R. C. Myers, S. Mack +8
We report infrared studies of the insulator-to-metal transition (IMT) in GaAs doped with either magnetic (Mn) or non-magnetic acceptors (Be). We observe a resonance with a natural…
Phonon splitting and anomalous enhancement of infrared-active modes in BaFeAs
A. A. Schafgans, B. C. Pursley, A. D. LaForge +3
We present a comprehensive infrared spectroscopic study of lattice dynamics in the pnictide parent compound BaFeAs. In the tetragonal structural phase, we observe the two d…
Electronic correlations and unconventional spectral weight transfer in BaFeCoAs
A. A. Schafgans, S. J. Moon, B. C. Pursley +7
We report an infrared optical study of the pnictide high-temperature superconductor BaFeCoAs and its parent compound BaFeAs. We demonstrate that…
Optical characterization of BiSe in a magnetic field: infrared evidence for magnetoelectric coupling in a topological insulator material
A. D. LaForge, A. Frenzel, B. C. Pursley +4
We present an infrared magneto-optical study of the highly thermoelectric narrow-gap semiconductor BiSe. Far-infrared and mid-infrared (IR) reflectance and transmission mea…
