摘要:

一个通用的过程已经开发出几乎无缺陷阵列(异质结构)的InP和GaP纳米线。软纳米压印光刻已用于在全2英寸基板上图案化金颗粒阵列。在剥离之后,有机残留物保留在表面上,这诱导另外的不期望的纳米线的生长。我们表明,在生长前用食人鱼溶液清洗样品,并结合在550 ℃下对InP和700 ℃下对GaP进行热退火,可以得到均匀的纳米线阵列,纳米线长度变化为1%,并且没有不希望的额外纳米线。我们的化学清洗程序适用于其他光刻技术,如电子束光刻,因此代表了一个通用的过程。

英文摘要:

A generic process has been developed to grow nearly defect free arrays of (heterostructured) InP and GaP nanowires. Soft nanoimprint lithography has been used to pattern gold particle arrays on full 2 inch substrates. After lift-off organic residues remain on the surface, which induce the growth of additional undesired nanowires. We show that cleaning of the samples before growth with piranha solution in combination with a thermal anneal at 550 C for InP and 700 C for GaP results in uniform nanowire arrays with 1% variation in nanowire length, and without undesired extra nanowires. Our chemical cleaning procedure is applicable to other lithographic techniques such as e-beam lithography, and therefore represents a generic process.
