我们通过实验证明了库仑封锁测温在60k温度下的精确实现。使用电子束光刻技术的纳米制造方法的进步使我们能够制造足够小的隧道结的均匀阵列,以保证总体温度读取精度约为1%。
We demonstrate experimentally a precise realization of Coulomb blockade thermometry working at temperatures up to 60 K. Advances in nano-fabrication methods using electron beam lithography allow us to fabricate uniform arrays of sufficiently small tunnel junctions to guarantee an overall temperature reading precision of about 1%.
