Detection of highly conductive surface electron states in topological crystalline insulators Pb(1−x)Sn(x)Se using laser terahertz radiation

We suggest a method for detection of highly conductive surface electron states including topological ones. The method is based on measurements of the photoelectromagnetic effect using terahertz laser pulses. In contrast to conventional transport measurements, the method is not sensitive to the bulk...

description We suggest a method for detection of highly conductive surface electron states including topological ones. The method is based on measurements of the photoelectromagnetic effect using terahertz laser pulses. In contrast to conventional transport measurements, the method is not sensitive to the bulk conductivity. The method is demonstrated on an example of topological crystalline insulators Pb(1−x)Sn(x)Se. It is shown that highly conductive surface electron states are present in Pb(1−x)Sn(x)Se both in the inverse and direct electron energy spectrum.
