The outstanding properties of graphene-based components, such as twisted graphene, motivates nanoelectronic researchers to focus on their applications in device technology. Twisted graphene as a new class of graphene structures is investigated in the platform of transistor application in this research study. Therefore, its geometry effect on Schottky transistor operation is analyzed and the relationship between the diameter of twist and number of twists are explored. A metal–semiconductor–metal twisted graphene-based junction as a Schottky transistor is considered. By employing the dispersion relation and quantum tunneling the variation of transistor performance under channel length, the diameter of twisted graphene, and the number of twists deviation are studied. The results show that twisted graphene with a smaller diameter affects the efficiency of twisted graphene-based Schottky transistors. Additionally, as another main characteristic, the ID-VGS is explored, which indicates that the threshold voltage is increased by diameter and number of twists in this type of transistor.

Abstract In this paper we investigate a new {(\alpha,\beta)} -metric {F=\beta+\frac{a\alpha^{2}+\beta^{2}}{\alpha}} , where {\alpha=\sqrt{{a_{ij}y^{i}y^{j}}}} is a Riemannian metric; {\beta=b_{i}y^{i}} is a 1-form and {a\in(\frac{1}{4},+\infty)} is a real scalar. Also, we investigate the relationship between the geodesic coefficients of the metric F and the corresponding geodesic coefficients of the metric α.

We analyse waves propagating along the interface between half-spaces filled with a perfect dielectric and a Lorentz material. We show that the corresponding interface condition leads to a generalization of the classical Leontovich condition on the boundary of a dielectric half-space. We study when this condition supports propagation of (dispersive) surface waves. We derive the related dispersion relation for waves along the boundary of a stratified half-space and determine the relationship between the loss parameter, frequency and wavenumber for which interfacial waves exist. This article is part of the theme issue ‘Modelling of dynamic phenomena and localization in structured media (part 1)’.

Language Assessment Literacy (LAL) research has focused on defining the knowledge, skills, and principles that the stakeholders involved in language assessment activities are required to master. However, there is scarce research on the relationship between LAL and the professional development of language teachers. Therefore, this exploratory action research study examined the impact of a language assessment course on pre-service teachers in a Colombian language teaching programme. Data were collected through questionnaires, interviews, teacher and researcher journals and class observations. The findings show that the course promoted theoretical, technical and operational dimensions in the language assessment design practices of the participants. In addition, it enhanced their LAL and professional development. Consequently, this study contends that the LAL course changed language assessment perceptions radically and encouraged pre-service teachers to design assessments conscientiously, a feature not explicitly stated in LAL research involving this group of stakeholders elsewhere.

Scale Length

We propose an analytical model for subthreshold swing using scale length for sub-10 nm double gate (DG) MOSFETs. When the order of the calculation for the series type potential distribution is increased it is possible to obtain accuracy, but there is a problem that the calculation becomes large. Using only the first order calculation of potential distribution, we derive the scale length λ1 and use it to obtain an analytical model of subthreshold swing. The findings show this subthreshold swing model is in concordance with a 2D simulation. The relationship between the channel length and silicon thickness, which can analyze the subthreshold swing using λ1, is derived by the relationship between the scale length and the geometric mean of the silicon and oxide thickness. If the silicon thickness and oxide film thickness satisfy the condition of (Lg-0.215)/6.38 > tsi(=tox), it is found that the result of this model agrees with the results using higher order calculations, within a 4% error range.

The benefits and longer term impact in the relationship of a starting entrepreneur and his/her mentor are the subject of research from the perspective of the entrepreneur. Most research study the effects of mentoring on the benefits, during or shortly after ending the mentorship relation; this study focuses on the redefinition of the relationship. Results show that the benefits are determined by the experienced psychosocial support the entrepreneur experiences, the amount of trust and the intensity. Longer term impact is determined by the experienced benefits, not by the mentoring activities; the specific situation of an entrepreneur compared to a mentee in an organization could explain this finding.
