By considering the Moore–Gibson–Thompson (MGT) equation, current work introduces a modified fractional photothermal model. The construction model is based on proportional Caputo derivative, which new definition of derivative that simple and works well. In addition, theory heat transfer in semiconductor materials was used context optical excitation plasma processes. proposed to investigate inter...

Semiconducting polymer heterostructures with strong two-dimensional quantum confinement of excitons are prepared by self-assembly of two conjugated polymers in binary blends. Exciton confinement effects in the semiconducting polymer quantum wires were observed at room temperature by photoluminescence excitation and photoluminescence spectroscopies and by electric field-induced photoluminescence...

In this thesis innovative tunnel devices based on new architectures, new fabrication approaches and novel material combinations are fabricated and investigated in detail. In particular, nanowire homoand heterojunction tunnel diodes based on Si and InAs-Si have been demonstrated for the rst time. The gained knowledge and understanding of tunnel diodes is applied to design and fabricate InAs-Si h...

Rhenium disulfide (ReS2) is a semiconducting two-dimensional material with marked in-plane structural anisotropy. This lattice anisotropy the stem of many quasi-1D properties observed in this material. In work, we focus on strain engineering optical and vibrational through mechanical deformations lattice. particular, exciton energy can be shifted by applying uniaxial strain, gauge factor six ti...

One of the critical issues for the application of single-wall carbon nanotubes (SWCNTs) in nanoelectronics is the control of their electronic properties, which can be either metallic or semiconducting in their pristine form, depending on their diameter and chirality. Since all known preparative methods yield mixtures of metallic and semiconducting nanotubes, extensive research has been devoted ...

The effect of vacancy and water adsorption on the electronic structure semiconducting 2D trichalcogenide material CrPX$_3$ (X: S, Se) is studied using state-of-the-art density functional theory (DFT) approach. It found that chalcogen vacancies play a minor role in vicinity Fermi level leading to slightly reduced band gap for these materials, however, inducing strongly localised defect states wh...
