Optical Properties of III-Mn-V Ferromagnetic Semiconductors
K. S. Burch, D. D. Awschalom, D. N. Basov
We review the first decade of extensive optical studies of ferromagnetic, III-Mn-V diluted magnetic semiconductors. Mn introduces holes and local moments to the III-V host, which c…
Electrodynamics of the vanadium oxides VO2 and V2O3
M. M. Qazilbash, A. A. Schafgans, K. S. Burch +5
The optical/infrared properties of films of vanadium dioxide (VO2) and vanadium sesquioxide (V2O3) have been investigated via ellipsometry and near-normal incidence reflectance mea…
Impurity Band Conduction in a High Temperature Ferromagnetic Semiconductor
K. S. Burch, D. B. Shrekenhamer, E. J. Singley +7
The band structure of a prototypical dilute ferromagnetic semiconductor, GaMnAs, is studied across the phase diagram via optical spectroscopy. We prove that the Fermi…
Ellipsometric study of the Electronic Structure of GaMnAs and LT-GaAs
K. S. Burch, J. Stephens, R. K. Kawakami +2
We have measured the optical constants of GaMnAs from 0.62 eV to 6 eV, using spectroscopic ellipsometry. The second derivatives of the dielectric function are examined through a cr…
