| Summary: | 碩士 === 南台科技大學 === 電機工程系 === 93 === From the results of low temperature specific heat), p-type 214 superconductor shows a d-wave behavior (C(T)=A/T2+γT+αT2+βT3). However, n-type 214 superconductor is not clear. Therefore we are strong interesting in investigating the electronic transportation mechanism of Pr2-xCexCu1-yMyO4 by doping magnetic and nonmagnetic atoms, and also comparing with p-type Pr2-xCexCu1-yMyO4.
In this thesis, we synthesis Pr2-xCexCu1-yMyO4(M=Zn、Ni，x=0.13、0.14、0.15、0.16、0.17，y=0、0.0025、0.005、0.0075、0.01) electronic superconductors using Solid State Reaction method and investigate the electronic properties of these samples with magnetic and non-magnetic dopants substituting Cu of samples. We also study the influence of various doping concentrations in superconductors on Tc and electronic properties.
