Abstract

We study the growth of nanowire arrays based on InAsP on silicon substrates. It was found that during the growth process two structural phases are formed: a cubic structure of the sphalerite type and a hexagonal structure of the wurtzite type. The epitaxial relations between InAsP and Si were determined: [0001]_NWs || [111]_Si, [\(11\bar {2}0\)]_NWs || [\(1\bar {1}0\)]_Si. A decrease of the radial growth rate and the formation of an axial heterojunction were revealed with the formation of thin (<100 nm) segments of the InAs_{1 –} _xP_x solid solution and maintaining a sufficiently high partial pressure of the As flow (at least 50%).

基于 InAs1 - xPx 固溶体在 Si(111) 上形成单层和异质结构纳米线

摘要我们研究了基于 InAsP 的纳米线阵列在硅衬底上的生长过程。研究发现，在生长过程中会形成两种结构相：闪锌矿型立方结构和钨矿型六方结构。确定了 InAsP 和硅之间的外延关系：[0001]NWs||[111]Si，[\(11\bar {2}0\)]NWs||[\(1\bar {1}0\)]Si。随着 InAs1 - xPx 固溶体薄片（100 nm）的形成，并保持足够高的 As 流分压（至少 50%），发现径向生长速率降低，并形成了轴向异质结。
