Controllable synthesis of Bi2S3 hierarchical nanostructures: Effect of addition method on structures

“…5d). Although the exact mechanism for the formation of cockscomb-like patterns is still under investigation, we speculate the growth of Bi 2 S 3 nanobelts may follow the solid-liquid-solid growth mechanism, which involves the formation and dissolution of amorphous flakes, the production of crystalline nano-nuclei, and the preferential growth of nanobelts [48].…”

Surface structure promoted high-yield growth and magnetotransport properties of Bi2Se3 nanoribbons

“…A promising approach to access the surface effects of the TIs is to reduce the size of material down to the nanoscale, thus increasing the surface to volume ratio. Nanostructures prepared by different techniques, such as chemical vapour deposition (CVD) 7 , sonochemical 8 and solvothermal 9 methods, catalysed vapour-liquid-solid 3,10,11 and catalyst-free physical-vapour deposition (PVD) 12–14 have been studied. However, most of the listed techniques have drawbacks associated with surface contamination of the nanostructures due to catalyst residues or low-crystalline structure due to the low process temperatures.…”

Synthesis and Quantum Transport Properties of Bi2Se3 Topological Insulator Nanostructures

“…Consequently, synthesis of high-quality Bi 2 Se 3 nanostructures is highly desirable. Various methods have been developed to fabricate Bi 2 Se 3 nanostructures, including mechanical exfoliation610, molecular beam epitaxial (MBE)111213, sonochemical methods21, solvothermal synthesis2022, metal-organic chemical vapor deposition23, and chemical vapor deposition (CVD)171819. Nevertheless, synthesis of Bi 2 Se 3 nanostructures with a variety of morphologies is still a challenge.…”
