Gate voltage modulation of the superconducting state in a degenerate semiconductor
Bikash C. Barik, Himadri Chakraborti, Buddhadeb Pal +6
In this work, we demonstrate that the modulation of carrier density can alter the superconducting transition temperature by up to mK in epitaxial Indium Nitride on Gallium Ni…
