Abstract

CVD diamond combines attractive properties for the fabrication of detection devices operating in specific environments. One inherent problem however with diamond is the presence of defect levels that are altering the detection characteristics. They result in unstable responses and carrier losses. One of the issues can be to operate the devices in the pulsed mode regime, when transitory effects are less impacted by defective levels evolution than for steady state currents. This therefore implies the use of materials that are faster, but also of lower carrier lifetime, and therefore generally agreed to be of poorer quality. This has therefore to be compromised with respect to the desired performances.
