High-speed photoconductivity of GaP light-emitting diodes at liquid-nitrogen temperature

Zusammenfassung

In GaP : N (Zn,Te) light-emitting diodes, extrinsic photoconductivity was excited by modelocked TEA CO2 laser pulses at liquid-nitrogen temperature, showing a current sensitivity of 2.10−5 A/W and a response time of the order of 0.5 ns.
