網頁2024年11月7日 · The growth maintained its step-flow mode with time without any visible pits on the surface. The rms is decreased to 0.049 nm, which, to the best of our knowledge, is the smallest reported so far for homoepitaxial … 網頁mode should be contrasted with growth without the nucle ation of islands, the traditional step flow mode, which is exppected to have a much more uniform surface morphology.
網頁2024年10月12日 · The noncleavage (010) plane has a relatively higher activation energy and is predicted to favor the step-flow growth mode, leading to excellent crystal perfection and high growth rate. [] In addition, the thermal conductivity along [010] direction is larger than thermal conductivity along [100] direction, [ 99 ] which gives better heat dissipation in … 網頁2024年10月31日 · A thermodynamic model for metalorganic vapor-phase epitaxy (MOVPE) of the N-polar $(000\\overline{1})$ binary group-III nitrides (AlN, GaN, and InN) in the step-flow growth mode is proposed based on the Burton, Cabrera, and Frank (BCF) theory. The coverages of the group-III adatoms are thermodynamically evaluated under competitive …
網頁2013年8月12日 · Ga-rich conditions assure step-flow growth with atomically flat surface covered by doubly-bunched steps, as for Ga-polar GaN. Growth under N-excess however leads to an unstable step-flow morphology. Particularly, for substrates slightly miscut towards 10 1 ¯ 0 , interlacing fingers are covered by atomic steps pinned on both sides … 網頁2014年6月13日 · Unfortunately, we could not keep step flow growth mode at initial nucleation stage on off-axis substrates for long time (>10 hours). The step bunching happened during the step flow growth. The SEM observation shown in Figure 11 indicates that hexagonal nucleation was taking place in the wide terrace or at the edges of the …
網頁detailed growth mechanism is presented based on a layer-by-layer growth mode for the rod-shaped NWs and a step-flow growth mode for the tapered region of the pencil NWs. I. …
