Designing radio electronic systems for space purposes optimal by the criterion of reliability based on ultra-high-speed heterostructure nanoelectronics devices

In order to solve the problem of ensuring the required level of reliability of modern radio electronic systems for space, aviation and special purposes on the basis of ultra-high-speed heterostructure nanoelectronics devices, methodology was elaborated aimed at design, development and technological optimization of such devices. It is proposed to use a special efficiency preservation coefficient as the target function, which makes it possible to take into account parametric alterations within the assigned operational tolerance and is characterized by practice-oriented advantages in comparison with the so-called integral probability of performing the given functions. The problem of reduced accuracy in forecasting electrical properties of semiconductor structures in nanoelectronics devices with a low dimensional channel is solved. A gerontological physical and mathematical model for AlGaAs-heterostructure nanoelectronics devices with transverse transport was developed, which made it possible to solve the problem of limited applicability of the methods established by the classical statistical theory of reliability to ensure increased requirements to durability of such devices in electronic systems for space purposes operating in severe conditions and operating modes.
