Impact ionization in InSb probed by THz-pump THz-probe spectroscopy
Matthias C. Hoffmann, Janos Hebling, Harold Y. Hwang +2
Picosecond carrier dynamics in indium antimonide (InSb) following excitation by below-bandgap broadband far infrared radiation were investigated at 200 K and 80 K. Using a novel TH…
Modulation Doping of a Mott Quantum Well by a Proximate Polar Discontinuity
T. Higuchi, Y. Hotta, T. Susaki +2
We present evidence for hole injection into LaAlO3/LaVO3/LaAlO3 quantum wells near a polar surface of LaAlO3 (001). As the surface is brought in proximity to the LaVO3 layer, an ex…
Termination Control of the Interface Dipole in LaSrMnO/Nb:SrTiO (001) Schottky Junctions
Yasuyuki Hikita, Mitsuru Nishikawa, Takeaki Yajima +1
In order to investigate the interface termination dependence of perovskite band alignments, we have studied the Schottky barrier height at LaSrMnO/Nb:SrTiO…
Electronic structure of the SrTiO/LaAlO interface revealed by resonant soft x-ray scattering
H. Wadati, D. G. Hawthorn, J. Geck +11
We investigated the electronic structure of the SrTiO/LaAlO superlattice (SL) by resonant soft x-ray scattering. The (003) peak, which is forbidden for our "ideal" SL struc…
Negative Differential Resistance Induced by Mn Substitution at SrRuO3/Nb:SrTiO3 Schottky Interfaces
Y. Hikita, L. Fitting Kourkoutis, T. Susaki +3
We observed a strong modulation in the current-voltage characteristics of SrRuO/Nb:SrTiO Schottky junctions by Mn substitution in SrRuO, which induces a metal-insulator…
