Abstract
The preparation procedure and performance of Mn1.56Co0.96-xNi0.48CuxO4 (MCNC, x=0, 0.08, 0.16, 0.24) IR detectors were reported. By varying the content of Cu ratio, a series of MCNC films and IR detectors were fabricated. The results show that the substitution of Cu element can significantly reduces the resistance and device noise for detectors with specific thickness and size. The typical time constant of the detector is 20-40 ms. The MCNC IR detector with x=0.24 shows a detectivity (D*) of about 0.83107 cmHz1/2W-1, which is enhanced by about 130% in comparing to the x=0.00 one. Additionally, the ageing phenomenon of MCNC detector is discussed in general.
