Photo-induced demagnetization and polaron binding energy increase observed by mid-infrared pump-probe spectroscopy in ferromagnetic Ga$_{0.94}$Mn$_{0.06}$As (2004)

Kojima, E., Heroux, J. B., Shimano, R., Hashimoto, Y., Katsumoto, S., Iye, Y., ...

Time-resolved transmittance measurements performed on Ga$_{0.94}$Mn$_{0.06}$As in the vicinity of the Mn-induced mid-infrared absorption band are presented. Upon photo-excitation, a slow increase...

Non-parabolicity of the conduction band of wurtzite GaN (2003)

Syed, S., Heroux, J. B., Wang, Y. J., Manfra, M. J., Molnar, R. J., Stormer, H. L.

Using cyclotron resonance, we measure the effective mass, $m$*, of electrons in AlGaN/GaN heterostructures with densities, $n_{2D}\sim 1-6\times10^{12}$cm$^{-2}$. From our extensive data, we...
