Low Earth orbital atomic oxygen and ultraviolet radiation effects on polymers [PDF]

Because atomic oxygen and solar ultraviolet radiation present in the low earth orbital (LEO) environment can alter the chemistry of polymers resulting in degradation, their effects and mechanisms of degradation must be determined in order to determine ...

Atomic signatures of local environment from core-level spectroscopy in $\beta$-Ga$_2$O$_3$

, 2016
We present a joint theoretical and experimental study on core-level excitations from the oxygen $K$ edge of $\beta$-Ga$_2$O$_3$. A detailed analysis of the electronic structure reveals the importance of O-Ga hybridization effects in the conduction region.
