2007 (English) In: Materials Science Forum, Vols. 556-557, Trans Tech Publications, 2007, Vol. 556-557, p. 53-56 Conference paper, Published paper (Refereed) Abstract [en] We report on the growth of 4H-SiC epitaxial layer on Si-face polished nominally on-axis

Electrically active defects in n

We have studied intrinsic and impurity related defects in silicon carbide (SiC) epilayers grown with fast epitaxy using chemical vapor deposition in a vertical hot-wall reactor. Using capacitance transient techniques, we have detected low concentrations of electron traps (denoted as Z 1/2, EH6/7 and titanium) and hole traps (denoted as HS1 and shallow boron) in the n-type 4H–SiC epilayers.

2006/4/7The growth rate of the epitaxial layers was in the range 0.01–0.1 nm s −1. 6H-SiC and 4H-SiC planar substrates were used for epitaxy. 3C-SiC layers were grown at lower substrate temperatures (T = 1550 K) and Si-rich conditions, and then a-SiC was depositedT

Suppression of Al Memory Effect on Growing 4H

However, in p-type 4H-SiC CVD growth, it is found that memory effect is rather strong: the formerly deposited SiC (on wafer, susceptor or reactor wall) releases p-dopants acting as an additional doping source [1]. The severe case observed from the junction fieldN

Student Dissertations :: AIXTRON

The best results were achieved between 1,200 C and 1,350 C, as lower temperatures led to island growth and higher temperatures resulted in etching processes and side reactions with the SiC susceptor. Furthermore, the use of N 2 and H 2 as carrier gases was investigated.

Nanoporous 6H

Solar-to-hydrogen conversion efficiencies of water-splitting photocathodes using epitaxially grown p-type 4H-, 6H- and 3C-SiC were estd. in a two-electrode system without applying any external bias. By using electrode materials with small oxygen overpotentials as counter electrodes, the photocurrent became comparable to that obsd. in a three-electrode system with a suitable bias.
