- donor bound exciton complex in ZnO
Reflection spectroscopy
Why VCSELs andwhy quantum dots (QDs)?
InGaN insertions inGaN as
dense arrays ofQDs
Surface lasing incavities withoutDBRs:
Narrow line, superlinear growth in intensity,
singlemode character,
high threshold excitationdensity
AlGaN/GaN DBRs and their impacton
the threshold excitationdensity
Room temperature photopumpedVCSELs
Far-field patterns of lasing and spontaneous
emission
Efficient InGaN/GaN/AlGaNLEDs
Resonant-cavity LEDs as prototypes of
current-injectionVCSELs
