Special Issue Information

Dear Colleagues,

Nanophotonics and Nanoelectronics refer to nanometer feature size structures commensurate with the wavelength of light or electrons and offer unique advantages when they are being used to manage light and electrons movement and localisation. The materials that are used to realise such structures tend to be metals and dielectrics (including semiconductors and insulators). Some of the interesting topics in these fields include:

Structures to control guiding, confinement and dispersion of light, including photonic-integrated circuits on silicon, and those involving compound semiconductor active structures integrated on to such a platform for active photonics.

Photonic cavities in which high Q are achieved enable new properties of light–mater interactions to be studied and harnessed. Nanostructures in which guided light modes interact nonlinearly can enable novel photonic structures to be built, including those being studied for the manipulation of quantum information.

Standing wave and open nanostructured cavities, when combined with plasmonics, present a fascinating medium for broadband surface-enhanced Raman structures, as well as for near-field spectroscopy and microscopies.

Electronic nanostructures include 2D materials, nanowires, quantum-confined heterostructures and reveal fascinating properties from traditional quantum transport to correlated effects, including spintronics, and Majorana Fermions.

The design of nanostructures for quantum information is a burgeoning field that looks to control over electrons degrees of freedom by local and global interactions.

In many of the cases of both photonic and electronic artificial nanostructures, surfaces and interfaces and their control play an important role in determining behaviour.

You are all invited to submit a manuscript for this Special Issue, in the form of research papers, communications, or reviews.

The performance of devices fabricated from piezoelectric semiconductors, such as sensors and actuators in microelectromechanical systems, is superior; furthermore, plate structures are the core components of these smart devices. It is thus important to analyze the electromechanical coupling properties of piezoelectric semiconductor nanoplates. We established a nanoplate model for the piezoelectric semiconductor plate structure by extending the first-order shear deformation theory. The flexural vibrations of nanoplates subjected to a transversely time-harmonic force were investigated. The vibrational modes and natural frequencies were obtained by using the matrix eigenvalue solver in COMSOL Multiphysics 5.3a, and the convergence analysis was carried out to guarantee accurate results. In numerical cases, the tuning effect of the initial electron concentration on mechanics and electric properties is deeply discussed. The numerical results show that the initial electron concentration greatly affects the natural frequency and electromechanical fields of piezoelectric semiconductors, and a high initial electron concentration can reduce the electromechanical fields and the stiffness of piezoelectric semiconductors due to the electron screening effect. We analyzed the flexural vibration of typical piezoelectric semiconductor plate structures, which provide theoretical guidance for the development of new piezotronic devices. Full article
