Paper Abstract

Photovoltaic CMT-Si CCD hybrid focal plane arrays for the Infrared Array Camera IRAC currently developed at ESO have been tested. The arrays have a format of 32 x 32 and 64 x 64 pixels. The cutoff wavelength of the detector is 3.9 microns but can be custom designed between 2.5 and 5 microns. The detectors consist of cylindrically shaped p-n junctions which are connected to a buried channel CCD by a special loophole interconnect technology. The input stage of the CCD is a direct injection circuit. Test results of the arrays relevant to ground based astronomy will be discussed and data on efficiency, fill factor, dark current, limiting noise performance and uniformity are presented. The tests were performed on reject engineering arrays. Scientific arrays are under development. Yet, test results obtained so far are promissing and demonstrate the potential of these devices for IR astronomy.
