This study introduces a method for creating Ohmic contacts to tin oxide (SnO2) by subjecting the sample surface to hydrogen plasma treatment at moderate temperatures of about 300 °C. This process generates a surface layer of metallic tin droplets, forming suitable electrical contacts. The contacts exhibit remarkable durability and demonstrate Ohmic behavior down to liquid helium temperatures.

氢等离子体处理产生的 SnO2 欧姆接触


本研究介绍了一种通过在约 300 °C 的中等温度下对样品表面进行氢等离子体处理来与氧化锡 (SnO2) 建立欧姆接触的方法。该过程产生金属锡滴表面层，形成合适的电接触。这些触点表现出卓越的耐用性，并在液氦温度下表现出欧姆行为。
