Description
  • Prezentuje se fotoluminiscence AlGaAs typu p, připraveného metalorganickou epitaxí z plynné fáze, intrisicky dopovaného uhlíkem (~ 2x1017 cm-3). Kromě linií způsobených mělkými příměsemi (C a Si) je pozorován strukturovaný pás 300 meV pod energií zakázaného pásu. Termální excitační energie a selektivní excitační závislosti strukturovaného pásu ukazují, že jeho původ má vztah k centrům DX–, které jsou vytvářeny optickým nabíjením atomů Si+ (cs)
  • Photoluminescence of p-type AlGaAs grown by metal-organic vapor-phase epitaxy and doped with intrinsic carbon (~ 2x1017 cm-3) is reported. Besides the lines related to the shallow impurities (C and Si), a structured band is observed 300 meV below the band gap. The thermal excitation energy and the selective excitation dependences of the BB gave evidence that its origin is related to the DX– centers produced by optical recharging of Si+ atoms.
