摘要
有更高超导的转变温度的重重地做硼的厚钻石电影被选举准备了帮助化学蒸汽免职方法。扫描电子显微镜学，拉曼光谱学， X 光衍射，和霍尔效果的结果显示榆树有好水晶的方面，处于生长率的著名减少，和张力的压力的增加。同时，电影抵抗力随搬运人集中的增加减少。我们的大小证明有 4.88 x 10 的榆树(20 ) 厘米(-3) 和 1.61 x10 (21 ) 厘米(-3) 搬运人集中有超导性，与 9.7K 的发作温度(8.9Kfor 零个电阻) 并且 7.8K (为零个电阻的 6.1K ) 分别地。
Heavily boron-doped thick diamond films with higher superconducting transition temperatures have been prepared by electron assisted chemical vapour deposition method. The results of scanning electron microscopy, Raman spectroscopy, x-ray diffraction, and Hall effect indicate that the films have nice crystalline facets, a notable decrease in the growth rate, and an increase in the tensile stress. Meanwhile, the film resistivity decreases with the increase of the carrier concentration. Our measurements show that the films with 4.88×10^20 cm^-3 and 1.61×10^21 cm^-3 carrier concentration have superconductivity, with onset temperatures of 9.7 K （8.9K for zero resistance） and 7.8 K （6.1 K for zero resistance）, respectively.
