Innovative Nanostructured Semiconductors for Electronic Devices

Dear Colleagues,

Semiconductor materials represent a milestone, and have served as a foundation from which electronic devices have evolved in recent decades. The microelectronic industry is based on the silicon element, with Moore’s Law ended up almost two decades ago and technology scaling approaching its inner physical limits (3 to 2 nm next resolution upgrade). Therefore, electronic device research is strongly oriented toward the realization of innovative transistors based on 2D materials for power efficiency and flexibility or toward energy and sensing applications.

The demand for more power-efficient and flexible transistors has pushed forward research on excitonic and valleytronic transistors based on 2D materials, such as graphene and transition-metal dichalcogenides (TMDs). These materials cointegrated with CMOS technology would widen the design possibilities at the level of the single logical block, while the search for higher energy conversion efficiencies has driven an incredible scientific effort to create a new class of materials, such as hybrid perovskites, whose superior performances in charge collection is also pushing photodetector research to new frontiers. The other major challenge of semiconductor-based device research is the ability to find ecological pathways for their synthesis and subsequent functionalization at large scale and low cost, in order to create a “real green economy”.

The aim of this Special Issue is to provide a unique international platform for scientists to publish their latest advancements on the following main topics:

• Novel forms of semiconducting materials such as nanoparticles, nanosheets, nanorods, quantum dots for energy, and sensing applications;
• Three-dimensional surface and bulk restructuring/modification of semiconductive materials for the control of light-trapping and surface transport properties;
• Physical, chemical, and optical characterization of semiconductive nanomaterials and exploitation of their outstanding features for device fabrication and integration in complex systems;
• Novel procedures for the synthesis of semiconductor nanomaterials that are low-toxicity and low-cost procedures.

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.
