特刊涵盖主题

Low-dimensional nanostructures are of particular interest with respect to their potential applications in highly integrated devices and systems. On-structure synthesis of nanowires or 2D materials with radially or axially modulated compositions along a single structure by a traditional chemical vapor deposition approach, especially for the gradient bandgaps along a single nanowire, is a formidable challenge in nanotechnology. That is because of the poor controllability of the solid-source in a vacuum tube under high temperature. Therefore, an innovative technical is urgently needed to realize the bandgap engineering on a single nanowire or 2D materials, which may provide material platforms for novel integrated optoelectronic devices and circuit. For example, composition graded nanowires with tunable bandgaps can suggested for broad band photodetectors, micro-spectrometer on-a-wire, and solid-state light sources. Heterostructure wires with abrupt interface and type-II energy band are promising idealized materials, which can provide multiple gain materials and serve as resonant cavities for multi-wavelength lasers.
