WebDec 6, 2024 · In this work, GO was used as a hole transport buffer layer, and ZnO was used as an electron transport buffer layer. The VFQDSCs with an active area of 0.44 … WebNew samples were prepared with an AlN buffer layer below the graphene layer to investigate this. The cubic AlN layer was grown with an Al flux of 1.4 × 10 14 atoms [cm 2 s] −1 and had a thickness of ≈10 nm, which was confirmed by X-ray reflection measurements. This is below the critical thickness, that is, the AlN layer should have grown ...

WebFeb 17, 2011 · A promising strategy for the selective growth of ZnO nanorods on SiO2/Si substrates using a graphene buffer layer in a low temperature solution process is described. High densities of ZnO nanorods were grown over a large area and most ZnO nanorods were vertically well-aligned on graphene. Furthermore, selective growth of … WebJan 26, 2024 · Heilmann et al. presented single-layer graphene as an atomically thin buffer layer for c-axis-oriented growth of vertically aligned GaN nanorods mediated by nanoscale AlGaN nucleation islands . Despite the growing interests in the heteroepitaxy of GaN films on graphene, there have been limited studies aimed at understanding the initial ... WebApr 12, 2024 · Surrounding the growth of graphene nanosheets is a protective buffer layer that nullifies any substrate-dependent features that could interfere with uniform morphology. Removal of this buffer layer, achievable through etching techniques such as H or OH radicals, benefits the growth of VG nanosheets .
