摘要:

本文报道了一种由自顶向下的纳米纤维方法制备的少层黑磷厚度图案。这是通过一种新的湿法蚀刻工艺实现的,该工艺可以以原子层精度蚀刻少数层黑磷的选定区域。该方法是深紫外和电子束光刻工艺兼容的,并且不含氧和其他常见的掺杂源。为大规模制备少层BP材料和器件提供了一种可行的图形化方法。

英文摘要:

This paper reports a few-layer black phosphorus thickness pattern fabricated by a top-down nanofabrication approach. This was achieved by a new wet etching process that can etch selected regions of few-layer black phosphorus with an atomic layer accuracy. This method is deep-UV and e-beam lithography process compatible,and is free of oxygen and other common doping sources. It provides a feasible patterning approach for largescale manufacturing of few-layer BP materials and devices.
