Effect of pressure on the semipolar GaN (10-11) growth mode on patterned Si substrates |
SEM image shows the high pressure (1013 mbar) growth of (10-11) GaN on the patterned Si (001) substrate with different growth temperatures: (a) plan view SEM and (c) cross-section SEM of the sample grown at 1190 °C, (c) plan view SEM and (d) cross-section view SEM of the sample grown at 1150 °C. |
