Temperature relations of Volt-Ampere characteristics of light emitting patterns GaP
Nuclear Physics and Atomic Energy, 2004 It is designed the improved methodology of Volt-Ampere characteristics (VACh) measurement with the opportunity of the settings of measurings discrete discretization step of both on the electrical voltage and on the current. It is revealed that the shape of VACh GaP structures essentially depends on the mode of measurings. S-shaped character of VACh and
