The new composites and nanostructures of group IV materials provide a platform for advanced devices for nanoelectronics, photonics and sensors. This Special Issue will focus on aspects of nanotechnology associated with silicon and other group IV semiconductors. Different issues relevant to low-dimensional structures, such as nanowires, nanocrystals and nanopores or nanosheets, are potential topics. Both their fabrication, such as lithography, processing, physical approach, chemical etching, nanoparticle formation, and their application in devices, are subject of interest. In particular, group IV nanostructures implemented in photonic devices, such as detectors, light emitting sources, waveguides, optical modulators and photovoltaic cells, will be encouraged. Another point is the application of group IV nanostructures in the field of biological and chemical sensing and their impact on sensing performances. Moreover, defect characterization, engineering and the impact of crystal quality on the properties of electronic and photonic devices are topics for this issue. This Special Issue of Nanomaterials will attempt to cover the most recent advances in group IV nanostructures, from synthesis and characterization to devices for photonics, nanoelectronics and sensors applications.
