ABSTRACTThe ion bombardment effects of low energy molecular nitrogen ions (100eV) on GaAs have been investigated using in-situ polar angle dependent X-ray photoelectron spectroscopy. It was found that arsenic and gallium nitrides were formed as a result of the nitrogen ion bombardment. The ion bombardment also caused a depletion of arsenic in the near surface region. For example, with a dose of 6×1015 cm-2 of nitrogen molecular ions at 100eV, the surface structure can be described approximately as 1.5nm of Ga0.67A0.33N on GaAs. The ion bombardment moves the Fermi levels of both n-type and p-type GaAs to mid-gap. Heating the ion bombarded samples in a vacuum chamber to 500°C desorbs all arsenic nitrides but most of the gallium nitrides remain on the surface. The Fermi levels of both n-type and p-type are then stablized at about 0.4eV from the valence band maximum. A surface type-inversion of the n-type substrate is therefore induced by the nitrogen-ionbombardment/annealing treatment.

This article presents the results of a theoretical study of self-realisation, self-actualisation and self-efficacy phenomena. The main aspects of understanding and correlating these phenomena in classical and modern Russian and foreign psychology are described. The highlighted concepts related to the phenomenon of self-realisation, both in the field of psychology and pedagogy. The similarities and differences of the self-realisation, self-actualisation, self-efficacy phenomena, as well as their correlation and comparison are presented. A comparative analysis of the studied concepts is given. According to the results of the theoretical analysis, the processes of self-realisation and self-actualisation are based on the inner motivation of a person to grow, develop personality, realise its potential. Both of these processes, due to their subjectivity, are difficult to observe and measure from the outside. We have highlighted the main differences, consisting in a greater awareness and orderliness of the process of self-realisation, as well as its predominantly "social" orientation, while self-actualisation is often associated with the struggle with external forces, the desire for self-realisation is rather approved and supported by the society. The concepts of self-realisation and self-efficacy are united by their inherent representation in the external plane of the life of the individual, as well as awareness, activity, goal-setting, and an orientation towards achieving success. In contrast to self-efficacy, self-release is a process rather than a sustainable phenomenon, and can be expressed both externally and internally through a connection with the value-semantic, motivational spheres of the individual.

Theoretical Results

Aiming at the experimental test of the body freedom flutter for modern high aspect ratio flexible flying wing, this paper conducts a body freedom flutter wind tunnel test on a full-span flying wing flutter model. The research content is summarized as follows: (1) The full-span finite element model and aeroelastic model of an unmanned aerial vehicle for body freedom flutter wind tunnel test are established, and the structural dynamics and flutter characteristics of this vehicle are obtained through theoretical analysis. (2) Based on the preliminary theoretical analysis results, the design and manufacturing of this vehicle are completed, and the structural dynamic characteristics of the vehicle are identified through ground vibration test. Finally, the theoretical analysis model is updated and the corresponding flutter characteristics are obtained. (3) A novel quasi-free flying suspension system capable of releasing pitch, plunge and yaw degrees of freedom is designed and implemented in the wind tunnel flutter test. The influence of the nose mass balance on the flutter results is explored. The study shows that: (1) The test vehicle can exhibit body freedom flutter at low airspeeds, and the obtained flutter speed and damping characteristics are favorable for conducting the body freedom flutter wind tunnel test. (2) The designed suspension system can effectively release the degrees of freedom of pitch, plunge, and yaw. The flutter speed measured in the wind tunnel test is 9.72 m/s, and the flutter frequency is 2.18 Hz, which agree well with the theoretical results (with flutter speed of 9.49 m/s and flutter frequency of 2.03 Hz). (3) With the increasing of the mass balance at the nose, critical speed of body freedom flutter rises up and the flutter frequency gradually decreases, which also agree well with corresponding theoretical results.
