Band-tail shape and transport near the metal-insulator transition in Si-doped Al(0.3)Ga(0.7)As
Jennifer Misuraca, Jelena Trbovic, Jun Lu +5
In the present work, an infrared LED is used to photodope MBE-grown Si:Al(0.3)Ga(0.7)As, a well known persistent photoconductor, to vary the effective electron concentration of sam…

Measurement of the spin polarization of the magnetic semiconductor EuS with zero-field and Zeeman-split Andreev reflection spectroscopy
Cong Ren, J. Trbovic, R. L. Kallaher +4
We report measurements of the spin polarization (\textbf{\textit{P}}) of the concentrated magnetic semiconductor EuS using both zero-field and Zeeman-split Andreev reflection spect…
