EFFECT OF TEMPERATURE ON RESISTANCE AND SPE- 

 CIFIC RESISTANCE OF TELLURIUM CRYSTALS 



ARTHUR R. FORTSCH 



In his Master's thesis Dr. Tisdale^ gives some resuUs on the ef- 

 fect of temperature on the resistance of tellurium crystals. He finds 

 a decided maximum at about zero degrees Centigrade. Inasmuch

as tellurium crystals are supposedly homogeneous it was considered 

 advisable to investigate the matter further. The crystals were 

 mounted by fusing platinum wires into the ends and placing the
