Beschreibungen/Notizen

• Room temperature terahertz (THz) emissions were observed from a single crystalline germanium (Ge) by photoluminescence mechanism. The emission mechanism can be explained by intracenter transition of antimony impurities in n-Ge. The emission spectrum contains two peaks corresponding to the 2Pplusmn rarr1S (T,A) (about 8.28 meV; 149.6mum), and 3P0 rarr1S (T,A) (about 7.45 meV; 166.3 mum) intra-center antimony transitions in n-Ge 1 .
