This program is concerned with the application of semiconducting materials to the problem of detection of electromagnetic radiation in the millimeter and submillimeter wavelength range. The method of approach involves the use of the internal photoelectric effect i.e., photoconductivity in certain semiconductor materials at very low temperatures. The program can be broken down into four main phases a investigation of indium antimonide in a magnetic field, b investigation of gallium arsenide andor indium arsenide in a magnetic field, c investigation of germanium and its behavior under stress, and d fabrication of experimental and breadboard model detectors. Photoconductivity and time constant measurements are continuing on various indium antimonide samples in a magnetic field. A breadboard model detector has been made and is in use testing gallium arsenide in magnetic fields up to 30 kilogauss. Author
