    You should have tried to help yourselves. Most of the answers are available from websites like Google and Wikipedia ..

    V defect

    High-resolution structural and chemical analyses of these “V-defects” by a number of complementary transmission electron microscopy techniques show that the InGaN quantum wells end abruptly at the V-defect interfaces, which lie on {10–11} planes. Each V-defect has at its center a threading edge dislocation, indicating that the defects are initiated at edge dislocation cores in the presence of indium. The lower temperatures of InGaN/GaN quantum-well growth (790 °C/950 °C) assist the formation of V-pits, which are subsequently filled in during the growth at higher temperature (1045 °C) of the p-type capping layer. © 2000 American Institute of Physics.

    RMS roughness

    Root-Mean-Squared is the value of the Alternative current commonly used to represent the system. Roughness could be due to many reasons.
