✦ Synopsis


We have investigated the voltage-temperature characteristics of p-n junction diodes and point contact diodes down to liquid helium temperatures. We observe that the current through these diodes plays a significant role in deciding the sensitivity as well as in limiting the temperature range of relatively linear response of the diodes when used as cryogenic temperature sensors. The interesting consequences of these observations are discussed.

Electrochemical characterization of Mg,Ni alloy was carried out at various temperatures. Discharge capacity of the Mg,Ni alloy electrode remarkably increased at 70Β°C and WC in comparison with that at 30Β°C. The charge-discharge curves as well as the measured pressure-composition isotherms revealed th
