In this paper, we study the edge effects on the electronic transmission of chiral silicene nanoribbons (CSiNRs) using the tight binding method and Green’s function approach. The investigation covers SiNRs of different chiralities and widths under t

Abstract Nanostructures exhibit unusual properties due to the dominance of quantum mechanical effects. In addition, the geometry of a nanostructure can have a strong influence on its physical properties. Using the tight-binding and force-constant app

Abstract Thermoelectrics as a way to use waste heat, is essential in electronic industries, but its low performance at operational temperatures makes it inappropriate in practical applications. Tailoring graphene can change its properties. In this wo

The Seebeck coefficient is an important quantity in determining the thermoelectric efficiency of a material. Phosphorene is a two-dimensional material with a puckered structure, which makes its properties anisotropic. In this work, a phosphorene nano

In a previous work, we introduced a new family of carbon cages, called fullerynes. Besides, we studied their stability by examining the vibrations of the infrared spectrum. But in this work, we intended to prepare a theoretical insight for experiment

Abstract The main contribution of this paper is to study the spin caloritronic effects in defected graphene/silicene nanoribbon (GSNR) junctions. Each step-like GSNR is subjected to the ferromagnetic exchange and local external electric fields, and t

Abstract The spin-dependent Seebeck effect (SDSE) and thermal spin-filtering effect (SFE) are now considered as the essential aspects of the spin caloritronics, which can efficiently explore the relationships between the spin and heat transport in th

Abstract In this study, based on density functional theory, we propose a new branch of pseudo-fullerenes which contain triple bonds with sp hybridization. We call these new nanostructures fullerynes, according to IUPAC. We present four samples with t

Using the tight-binding approach and non-equilibrium Green’s function method, we investigate the electronic band structure, total electronic heat capacity (EHC), and Pauli spin susceptibility (PSS) of zigzag MoS2/MoSe2 and MoS2/WSe2 hybrid nanoribb

In this paper, we introduce new features of silicon in fullerane structures. Silicon, when placed in a fullerane structure, increases its electron affinity and electrophilicity index, compared to placement in a diamondoids structure. These nanopartic
