Organic nanostructures made from organic molecules such as para-hexaphenylene (p-6P) could form nanoscale components in future electronic and optoelectronic devices. However, the integration of such fragile nanostructures with the necessary interface circuitry such as metal electrodes for electrical connection continues to be a significant hindrance toward their large-scale implementation. Here...
van der Waals junctions of two-dimensional materials with an atomically sharp interface open up unprecedented opportunities to design and study functional heterostructures. Semiconducting transition metal dichalcogenides have shown tremendous potential for future applications due to their unique electronic properties and strong light-matter interaction. However, many important optoelectronic ap...
The ability to detect light over a broad spectral range is central to practical optoelectronic applications and has been successfully demonstrated with photodetectors of two-dimensional layered crystals such as graphene and MoS2. However, polarization sensitivity within such a photodetector remains elusive. Here, we demonstrate a broadband photodetector using a layered black phosphorus transist...
We report the optoelectronic device properties of individual Au-silica hybrid nanowires prepared by microwave plasma enhanced chemical vapor deposition. Due to the surface plasmon resonance (SPR) effect the photo-responsivity peak strongly depends on the shape of the embedded gold nanostructures in the silica nanowire in which the shape can be modified by controlling the growth time of Au-silic...
An ultrahigh photosensitive diode was developed using a Cu-doped CeO 2 thin film through spray pyrolysis processing, which has made unique contribution in the field of optoelectronic device fabrication process.
Genetic algorithms are the search and optimization methods based on the principles of natural evolution. An optoelectronic implementation is proposed in this paper to realize a genetic algorithm. Based on binary logic operations, crossover and mutation of a population of chromosomes can be carried out in parallel, which is very suitable for optical implementation. An electron trapping device is...
Polymer composites are an attractive near-term means to exploit the unique properties of single wall carbon nanotubes and graphene. This is particularly true for composites aimed at photonic and optoelectronic applications, where a number of devices have already been demonstrated. These include transparent conductors, saturable absorbers, electroluminescent and photovoltaic devices. Here, we pr...
Cadmium telluride nanoribbons were synthesized electrochemically and formed into nanodevices using lithographically patterned nanowire electrodeposition (LPNE) that integrated synthesis and device fabrication together. By controlling the composition of the CdTe nanoribbons via adjusting the electrodeposition potential, electrical properties (i.e., electrical resistivity and field-effect transis...
We demonstrate in-situ Raman measurements of individual silicon nanowires (100 nm diameter, 10-20 m in length) which are trapped using optoelectronic tweezers (OET). OCIS codes: (300.0300) Spectroscopy, Raman; (140.7010) Trapping. Optoelectronic tweezers (OET) is a dynamic, non-invasive optical manipulation tool that works based on the principle of light-induced dielectrophoretic force. It is c...
