摘要
采用脉冲激光沉积技术 ,在n型SrNb0 0 1 Ti0 99O3(SNTO)单晶基片上生长p型YBa2 Cu3O7-δ(YBCO)薄膜 ,制备出YBCO SNTOp n结 .YBCO薄膜是高度c轴织构的超导薄膜 ,且具有良好的超导电性 .YBCO SNTOp n结具有较好的整流特性和很好的温度与磁场稳定性 .
A p-n junction is fabricated by using the pulsed laser deposition (PLD) technique for a p-type YBa2Cu3O7-δ (YBCO) film on the n-type SrNb0.01Ti0.99O3 (SNTO) single crystal substrate. The measured results reveal that the YBCO thin film is highly c-orientated structure and shows very good superconducting properties. The YBCO/SNTO p-n junction has good rectification property and stability under variation of temperature and magnetic-field.
