Special Issue "Nanomaterials: Ultrafast Optoelectronic Processes and Their Applications"

Dear Colleagues,

We are pleased to invite you to submit your original and review papers to this Special Issue of Nanomaterials focusing on ultrafast optical processes and the applications of nanomaterials.

Materials at low dimensional such as quantum dots, quantum wires, Van der Waals 2D materials, and conjugated molecules exhibit distinctive physical properties compared with their bulk counterparts. At a small dimension below the exciton Bohr radius, carrier–carrier interaction and light–matter interaction are significantly enhanced in the regime, namely, quantum confinement. Such strong quantum confinement in combination with ultrashort optical pulses results in many exotic physical properties, especially at a short time scale, including many-body interaction, phonon-bottleneck, multiple exciton generation, Auger interaction, enhanced emission rate, enhanced surface plasmonic resonance, lifting of the spin degeneracy and spin relaxation, quantum beating, and coherent oscillations.

Ultrafast optical spectroscopic techniques could reveal rich information on light–matter interaction at the nanoscale. With ultrashort light pulses, we can probe the dynamical motions of charges, spins, and lattices on femtosecond or even down to attosecond timescales. In addition, the nonlinear response of nanomaterials to intense laser fields induces various exotic phenomena, such as high harmonic generation, nonlinear magneto-electric nonlinearities, and materials phase transitions.

Those emerging properties at the nanoscale can lead to a vast number of applications in optoelectronics, spintronics, and flexible devices. That includes highly efficient light-emitting diodes, photodetectors, photovoltaics, photoresistors, and biophotonics, to name only a few.

This Special Issue highlights the recent advances in the study of ultrafast phenomena in nanomaterials, including 0D materials (molecules, quantum dots, and metal nanoparticles), 1D materials (CNTs, nanorods, nanowires, etc.), 2D materials (graphene, transition metal dichalcogenides, perovskites, Mxenes, etc.) and their applications enabling exotic properties. In addition, we would like to extend the topic to the area of light–matter interactions in nanomaterials assisted by optical nano/micro-cavities.

We welcome your contributions both in theoretical and experimental works to the above-related fields.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
