Abstract:
Thin films of Dirac semimetal Cd3As2 about 100 nm thick made of single crystals of cadmium arsenide, prepared by direct fusion of the elements by vacuum–ampoule method, by vacuum–thermal sputtering/depostion have been studied. Temperature and magnetic field dependences of electrical resistance have been measured, which indicate the presence of a superconducting transition at a temperature from 0.2 to 0.6 K.
Keywords:
Dirac semimetal, superconductivity, thin film.
The work was performed with the support of RSF project no. 17-12 01345. The national laboratory of strong magnetic fields (NHMFL, USA) is funded by the National Science Foundation (grant NSF/DMR-1644779) and the state of Florida.
