DENSITY AND BINDING-ENERGY OF MAGNETICALLY STABILIZED ELECTRON-HOLE LIQUID IN INDIUM-ANTIMONIDE

Main thermodynamic parameters of magnetic-field-stabilized electron-ho le liquid (EHL) in indium antimonide are determined as a function of m agnetic field strength from the shape and spectral position of its lum inescence line. It is found, that in the stability region of the liqui d phase (H >20 kOe) the EHL experiences self-compressing with the rise of magnetic field, and the binding energy per pair of particles, meas ured from the ground exciton level (work function) increases significa ntly. Zn the field range from 23 to 55.2 kOe the liquid density grows linearly from 3.5.10(15) to 7.3.10(15) cm(-3), and the work function i ncreases from 0.36 to 1.2 meV with the increase of magnetic field stre ngth.
