(Plasmonic metal)/semiconductor hybrid nanostructures are currently of increasing interest owing to their rich and attractive physical and chemical properties derived from localized plasmon resonance and semiconduction. In this article, the preparation, properties, and applications of this type of hybrid nanostructure are reviewed. Future directions in this field are also discussed.

Artificial superlattice nanocomposites are successfully prepared by electrostatic heteroassembly of redoxable Co–Al or Co–Ni layered double hydroxide (LDH) nanosheets with graphene. The superlattice electrodes exhibit a high capacity up to ca. 650 F/g, which is approximately 6 times that of pure graphene. The composites are found to be capable of superfast charging and discharging, up to ca. 100 Hz, comparable with the high-power performance of graphene electrodes.

High-performance optoelectronic devices based on cup-stacked carbon nanotubes are realized. Based on a Schottky barrier model, rectifying behaviors and high photoresponse are observed by using growth catalysts as nanoscale electronic contacts. Similar performances are also obtained and furthermore tuned by using the nanotube's defective surface as effective decoration sites transforming nanotube resistors into Schottky diodes.
- Effective Solution- and Vacuum-Processed n-Doping by Dimers of Benzimidazoline Radicals

Benzimidazoline radical dimers that can be handled in air but that function as powerful reductants are reported and evaluated as n-dopants by solution- and vacuum-processing. In several host materials, one of these dimers is found to have a more consistent doping effect than a hydride-donor dopant analog. Notably, a record high room-temperature conductivity of 12.0 S cm−1 is obtained for doped C60.
- Electric Field Manipulation of Magnetization Rotation and Tunneling Magnetoresistance of Magnetic Tunnel Junctions at Room Temperature

Electric-field-controlled tunneling magnetoresistance (TMR) of magnetic tunnel junctions is considered as the milestone of ultralow power spintronic devices. Here, reversible, continuous magnetization rotation and manipulation is reported for TMR at room temperature in CoFeB/AlOx/CoFeB/piezoelectric structure by electric fields without the assistance of a magnetic field through strain-mediated interaction. These results provide a new way of exploring electric-field-controlled spintronics.
