Synthesis of grass-like ZnSe nanostructures on graphene oxide and their excellent field emission properties

Morphology-controlled synthesis and electron field emission properties of ZnSe nanowalls

“…lists the turn-on elds and eld enhancement factors of different ZnSe eld emitters reported in the literature and from this work. The FE performance of the ZnSe nanowalls described here are generally comparable to other ZnSe nanostructures such as nanoribbons,40 nanoarrays, 42 nanoowers 43 and nanograsses 44. …”

Synthesis of grass-like SnO2 nanostructures on graphene oxide and their excellent field emission properties

“…The high dense distribution and good alignment of the SnO 2 nanograsses can increase the tip field-enhancement effect, and provide dense emission sites for good FE properties. Compared to allium mongolicum-like SnO 2 nanograsses, needle-like SnO 2 nanograsses have greater density and they are more close to perpendicular to the surface of GOs [22]. Thus, needle-like SnO 2 nanograsses have highly efficient fieldemission.…”

Synthesis, field emission of various ZnSe nanostructures by hydrothermal methods

“…Introduction: One-dimensional semiconductor nanostructures, such as nanowires, nanospheres, and nanotubes have attracted considerable attention in the field of optoelectronic nanodevices and catalysis in the last decade, due to their excellent optical and electrical properties [1]. ZnSe, as one of the most important group II-VI compounds materials, is regarded as a promising material in the fabrication of light-emitting diodes, solar cell and photodetectors because of its wide band gap (2.7 eV, at room temperature) and high exciton binding energy (21 meV) [2][3][4][5]. Subsequently, various one-dimensional ZnSe nanostructures are synthesised gradually via different methods, such as metal organic chemical vapour deposition, solvothermal method, thermal evaporation and laserassisted catalytic growth [6][7][8][9].…”
