Summary

STUDY OF ELECTRICAL AND SUPERCONDUCTING PROPERTIES OF BISMUTH FILMS DEPOSITED IN HYDROGEN ATMOSPHERE AT VERY LOW PRESSURES ON TO SUBSTRATES COOLED WITH LIQUID HELIUM. THE SOLUTED HYDROGEN BRINGS ABOUT ESSENTIAL ENHANCEMENT OF THE RESISTIVITY, DECREASE OF CRITICAL TEMPERATURE AND DECREASE OF THE AMORPHOUS -CRYSTAL TRANSITION TEMPERATURE. IF THE PRESSURE EXCEEDS A CERTAIN CRITICAL VALUE, THE FILMS PRODUCED ARE THE METASTABLE PHASE ALPHA-BISMUTH (H) SATURATED WITH HYDROGEN. AT 5 K THIS PHASE TRANSFORMS TO THE USUAL, ALSO METASTABLE, AMORPHOUS BISMUTH. IN THIS TRANSITION THE RESISTIVITY DROPS ABRUPTLY (BY A FACTOR OF TWO ORDERS) AND CRITICAL TEMPERATURE INCREASES (UP TO 2 K).
