Giant Seebeck effect across the field-induced metal-insulator transition of InAs
Alexandre Jaoui, Gabriel Seyfarth, Carl Willem Rischau +5
Lightly doped III-V semiconductor InAs is a dilute metal, which can be pushed beyond its extreme quantum limit upon the application of a modest magnetic field. In this regime, a Mo…

Charge Transport in a Polar Metal
Jialu Wang, Liangwei Yang, Carl Willem Rischau +6
The fate of electric dipoles inside a Fermi sea is an old issue, yet poorly-explored. SrCaTiO hosts a robust but dilute ferroelectricity in a narrow ($0.002<x<0.0…

A possible mechanism for superconductivity in doped SrTiO3
D. van der Marel, F. Barantani, C. W. Rischau
The soft ferro-electric phonon in SrTiO3 observed with optical spectroscopy has an extraordinary strong spectral weight which is much stronger than expected in the limit of a perfe…
