ABSTRACT:
A micro refrigerator includes two NIS, normal metal/insulator/superconductor tunnel junction refrigerators formed on a substrate connected in series in a SINIS structure, with a common normal metal element connected therebetween and the superconducting elements outside. The refrigerator includes an insulating membrane thermally isolated from the substrate, and the common normal metal element includes a protrusion extending to the insulating membrane, which refrigerates the insulating membrane and an object placed on the insulating membrane.
