Charge-state control of carbon-related optical absorption in AlN
Helen C. Robinson, Daniil Danilin, Md Shafiqul Islam Mollik +5
Sub-bandgap optical absorption in AlN between 2 eV and 4 eV is widely observed, but its microscopic origin remains contested. Using photo-induced electron paramagnetic resonance (p…

Direct evidence for carbon incorporation on the nitrogen site in AlN
Darshana Wickramaratne, Mackenzie Siford, Md Shafiqul Islam Mollik +2
We use photo-electron paramagnetic resonance (EPR) measurements and first-principles calculations to identify and explain the properties of carbon in AlN. We present clear evidence…
