| Abstract(in English) | It is important to raise the tunneling efficiency of quasiparticles generated by incident X-ray or photon for the operation of superconducting tunneling junction as the detector. Using the electron beam evaporation technique under the high-vacuum pressure of 4 x 10^<-9> Pa, we fabricate epitaxial Nb and Ta layers on a sapphire substrate at the substrate temperature of 500～700 ℃. Nb layer indicates the transition temperature(Tc)of ～9.3 K and the residual resistance ratio(RRR)of ～50. Ta layers indicates Tc～4.5 K and RRR of 45～140. |
