In the past years we have developed a method measuring carrier recombination lifetime in semiconductors using the photo-MuSR setup in HIFI. These studies have focused on... -
Muonium-photocarrier interaction in germanium
Having established the photo-MuSR method in intrinsic silicon to investigate excess carrier recombination lifetime and Mu-photocarrier dynamics in our previous experiments, we... -
A GENERAL METHOD OF MEASURING ANTIOXIDANT CAPACITY
Antioxidants are very important molecules because they can prevent or slow down the oxidative damage to our bodies. When our bodies use oxygen, free radicals are released which... -
