The thermal emf and the magnetoresistance of liquid selenium were measured with graphite electrodes in a pressure vessel up to 1300K. A sign change of the thermoelectric power was observed at about 990K. Above this temperature selenium is an n-type s

The electrical conductivity of liquid selenium was measured from the melting point up to appr. 800°C by an electrodeless method and above to appr. 1000°C with graphite as well as vitreous carbon electrodes. There exist three ranges with different a

Liquid selenium shows above 720°C a reversible switching from higher to lower conductance effected by an electric field. Below 720°C liquid selenium switches first to higher and then to lower conductance. After switching to low conductance, a volta

Liquid selenium shows above 720°C a detectable anomalous (positive and negative) magneto-resistance, which is dependent on the applied electric field. A positive magneto-resistance could be observed too below 720°C after switching to high conductan
