研究了单晶胞厚度YBa 2Cu 3 O 7-δ人工材料正常态和超导态的对角和霍尔介电常数（pxx和pxy）。YBa 2Cu 3 O 7-δ体材料中的一些输运性质是单个CuO 2导电双层膜的固有性质。给出了Kosterlitz-Escherloss电阻转变以及自由涡和反涡激发的证据
Diagonal and Hall resistivities (p xx and p xy ) in the normal and superconducting states are studied in one-unit-cell-thick YBa 2 Cu 3 O 7-δ artificial materials. A number of transport properties in bulk YBa 2 Cu 3 O 7-δ are shown to be inherent properties of the individual conducting CuO 2 bilayers. Evidence of Kosterlitz-Thouless resistive transition as well as the excitation of free vortex and antivortex is presented
