Influence of the PALE growth temperature on quality of MOVPE grown AlN/Si (111)
(02.02.2021)
In the present study, the PALE-AlN (pulsed atomic layer epitaxy) epilayers were grown on the Si (111) substrates
at different growth temperatures by metal organic vapor phase epitaxy (MOVPE) technique. The oxygen (O) ...
Nucleation layer temperature effect on AlN epitaxial layers grown by metalorganic vapour phase epitaxy
(20.09.2021)
AlN samples have been grown on sapphire substrate using nucleation layers
(NLs) having different growth temperatures. The growth temperature of the NL
has been varied over a wide range of temperatures highlight the effects ...
