Crystal Growth of Rare Earth Pnictides and ZnSe in W and Mo Crucible closed by Electron Beam Welding(Physics, Process, Instruments & Measurements)
Search this Article
New results in both high temperature technology and crystal growth in closed systems are reported. The key problem to attain ultra high temperature in a vacuum furnace was resolved by applying new excellent radiation shield made of Pyrolytic BN. Improvement is carried out on the structure of welding part of metal crucibles to prevent leakage from the closed crucible during heating. New results of the crystal growth of ZnSe which is rapidly rising the possiblities of blue light emitting diode. Physical properties of CeP and CeAs are reported. As new materials which show heavy fermion state in extremely low carrier concentrations are also presented.
