Size engineering optoelectronic features of C, Si and CSi hybrid diamond-shaped quantum dots

Abstract

Based on the density functional theory and many-body ab initio calculations, we investigate the optoelectronic properties of diamond-shaped quantum dots based graphene, silicene and graphene–silicene hybrid.

Interaction of hydrogen-edged boron nitride flakes with lithium: boron nitride as a protecting layer for a lithium-ion battery and a spin-dependent photon emission device

“…, of these three flakes are 3.28, 3.25, and 3.24 eV, respectively. Hence, the chemical stability of these flakes that is equal to µ 2 /(2η) can be calculated [40]. Accordingly, for pristine flakes chemical stabilities are 1.56, 1.60, and 1.63 eV, respectively.…”

Insights into the optoelectronic behaviour of heteroatom doped diamond-shaped graphene quantum dots

“…Additionally, we aim to investigate their potential in nanomedical applications, particularly in diagnostic devices and drug delivery systems, as well as their suitability for use in energy storage and conversion technologies. Based on our previous publications, [51][52][53][54][55] the shape of DSGQDs was found to have a considerable effect on the optoelectronic, excitonic and photoluminescence behaviours, especially upon functionalization. So exploiting these ndings, we focus on studying the special response of DS nanostructures to the heteroatom doping process and its associated factors as a function of the type and position of ve dopants, including zigzag or armchair corners, or inside the surface.…”

Two-dimensional quantum dots for biological applications

“…Recently, photoluminescent nanomaterials have attracted the interest of researchers due to their various applications in biology. For example, fluorescence imaging has been developed into in vivo and in vitro bioimaging of disease-associated tissues and cells, such as tumors, cancer, wound infection, and inflammation [132,[171][172][173][174][175].…”

“…Chemotherapy and radiotherapy are traditional cancer therapies. However, the obvious defects, including low selectivity, side effects, and ineffective treatment are another challenge to be solved [171,216]. 2D-QDs have been desired as a candidate for biological applications, because of the various advantages of luminescence, low toxicity, good biocompatibility as well as water solubility [14,27,217].…”
