The research is based on innovative techniques that have expanded the physical understanding of the process, which has improved the adequacy of the final results. Based on the developed physical modeling methodology, a study of the silicon epitaxial layers deposition process was carried out. The results were processed in a generalized form and could be represented by simple criterion relations. Based on the studies the area of the technological process with maximum possible homogeneity of silicon epitaxial layers deposition parameters was determined. It was shown that the silicon epitaxial layers deposition rate is determined by the interaction between the outgoing flow (from the nozzle) and reverse flow (at the moment when the wafer is between the nozzles). The use of the technique based on the autodopping effect showed that the distribution of the dopant impurity (from the local source) in the deposition zone is inhomogeneous and a significant part of the impurity is transferred in the direction of the jet flow. The plasma chemical deposition process of SiHxNy has been studied. As a defining parameter of the plasma chemical deposition process, the number ReL characterizing the gas dynamics of the process is chosen. Studies were performed at pressures in the reaction chamber of 100, 50, and 10 Pa, which corresponds to values ReL =1.2, 0.8, and 0.4. It is shown that greater uniformity of the deposited layer occurs at higher pressures.","PeriodicalId":388511,"journal":{"name":"International Conference on Micro- and Nano-Electronics","volume":"12157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130746919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The wave function formalism was applied in the development of numerical model of vertical heterostructures based on 2D materials [1, 2]. Combined self-consistent models [3, 4] were adapted for the case of taking into account vertical transport in the conduction band. The influence of various factors on the electric characteristics of the vertical heterostructures based on graphene, h-BN and MoS2 was investigated with the use of the developed model. The IVcharacteristics of such structures were calculated for different number of layers of 2D materials that forms potential barriers and quantum wells. Comparison of the results of simulation of the investigated structures is carried out. A numerical combined model based on a self-consistent numerical solution of the Schrödinger and Poisson equations in the active region of the device was used to calculate the IV-characteristics of GaN/AlGaN-based RTDs with vertical transport [5, 6]. The proposed model was used to study the effect of the aluminum concentration in the barriers on the IV-characteristics of the considered RTDs. Developed quantum drift-diffusion model of FET based on monolayer graphene was described in detail [7, 8]. The model is based on quantum drift-diffusion approximation of carrier transport. Graphene channel is located between topand back-gate dielectrics. With the use of the model simulation of dual-gate FET with channel width 18 μm was considered. A good agreement with experimental data was obtained for number of applied voltages. Adequacy of the model is confirmed by these calculations.
