Bulk samples of 0.15 As‐0.12 Ge‐0.73 Te glass were switched electrically with a voltage slightly above the threshold voltage. For a probe separation of 1.4 mm and the sample at room temperature, the threshold voltage is 150 V. The visual effects

Thin‐film platinum resistance thermometers have been made by rf sputter deposition and then used to measure film temperatures in situ during the sputtering process. They have been successfully used over a temperature range of −200° to +100°C. A

A dynamic pulse‐heating method has been developed for measuring with an error of less than 2% the specific heats of metal wires from room temperature to 1000°C. The method consists essentially of recording the resistance of the sample wire while i

The thermal diffusivity of five platinum samples with resistivity ratios of 12, 34, 100, 900, and 5000 has been measured from 300° to 1200°K. Only the sample with the resistivity ratio of 12 showed deviations of more than 3% from the average therma

The electrical resistivities of the nonstoichiometric compounds NaxWO3 have been measured as a function of sodium concentration from x=0.48 to x=0.88, and as a function of temperature from T=4°K to T=873°K. The minimum in electrical resistivity nea

A modified Angstrom method for measuring thermal diffusivity and hence thermal conductivity of metals has been developed. Like previously reported dynamic methods, this method uses a heat source, whose temperature varies sinusoidally with time, locat

Threshold‐switching measurements of synthetic melanin confirm that this organic semiconductor switches to a low‐resistance state in low electric fields as reported by McGinness et al. Time‐dependent current‐vs‐voltage curves show that the t

A combination of rf cosputtering and control of film temperature and film bias conditions have been investigated to determine the feasibility of obtaining films of many different compositions from a single main sputtering target. In the low Ge region
