FEATURES OF CURRENT TRANSFER IN n-GaPp-(InSb)1-x(Sn2)x HETEROSTRUCTURE
n-GaPp-(InSb)1-x(Sn2)x (0 х 0.05) heterostructures were fabricated and their current-voltage characteristics were studied. At low voltages V < 0.5 V the current-voltage characteristic is described by the exponential law: I = I0exp (qV / ckT) with an exponent c = 3.6, and at large voltage...

SOLUTION OF SYSTEMS OF LOGIC EQUATIONS IN RECOGNITION TASKS
In logical recognition systems, logical methods are used to construct the recognition algorithms based on discrete analysis and propositional calculus based on it. In the general case, the logical method of recognition provides for the presence of logical connections expressed through a system of...
