实验结果表明，垂直于外延正常导电YBa_2Cu_3 O_（7-δ）薄膜表面的温度梯度会引起薄膜表面接触点之间的大横向电压。 通过脉冲激光照射和通过加热丝对膜的连续加热来产生温度梯度。 为了解释大的横向电压，提出了一种原子层嗜热物质，它可能是由材料的层状结构形成的。
Experiments are reported which show that temperature gradients perpendicular to the surface of epitaxial normal conducting YBa2Cu3O7-delta films give rise to large transversal voltages between contacts on the film surface. The temperature gradients have been produced by pulsed laser irradiation and by continuous heating of the films by heater wires. To explain the large lateral voltages, an atomic layer thermophile is proposed, which may be formed by the layered structure of the material.
