Special Issue Information

Dear Colleagues,

The unique electrical properties of the large family of carbon allotropes, ranging from semi-metals to semiconductors and insulators, have sparked significant interest in the use of these materials for a wide range of electric applications. The large charge carrier mobility observed in both graphene and carbon nanotubes, together with the large maximum current density, makes them a promising candidate for electronic devices like field-effect transistors and interconnects. Diamond, on the other hand, is an excellent insulator but can also be used as a wide bandgap semiconductor and has, for instance, been considered for power electronics and qubits.

Besides their excellent electrical properties, the allotropes of carbon also have outstanding thermal, mechanical, and optical properties. Because of this, carbon-based electronic materials are of interest for a wide range of other electrical applications like sensors, flexible electronics, bioelectronics, and batteries, to name but a few.

This Special Issue will present recent advances in carbon-based electronic materials and their applications. Original and review articles can deal with the mentioned applications, without being limited to them, but can also focus on material deposition and characterization, doping, functionalization, and the integration challenges of carbon-based materials in existing (semiconductor) fabrication technologies.

I invite you to submit your manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

Dr. Sten Vollebregt

Since the transfer process of graphene from a dedicated growth substrate to another substrate is prone to induce defects and contamination and can increase costs, there is a large interest in methods for growing graphene directly on silicon wafers. Here, we demonstrate the direct CVD growth of graphene on a SiO2 layer on a silicon wafer by employing a Pt thin film as catalyst. We pattern the platinum film, after which a CVD graphene layer is grown at the interface between the SiO2 and the Pt. After removing the Pt, Raman spectroscopy demonstrates the local growth of monolayer graphene on SiO2. By tuning the CVD process, we were able to fully cover 4-inch oxidized silicon wafers with transfer-free monolayer graphene, a result that is not easily obtained using other methods. By adding Ta structures, local graphene growth on SiO2 is selectively blocked, allowing the controlled graphene growth on areas selected by mask design. Full article

An ethanol gas sensor based on carbon nanofibers (CNFs) with various densities and nanoparticle functionalization was investigated. The CNFs were grown by means of a Plasma-Enhanced Chemical Vapor Deposition (PECVD), and the synthesis conditions were varied to obtain different number of fibers per unit area. The devices with a larger density of CNFs lead to higher responses, with a maximal responsivity of 10%. Furthermore, to simultaneously improve the sensitivity and selectivity, CNFs were decorated with gold nanoparticles by an impaction printing method. After metal decoration, the devices showed a response 300% higher than pristine devices toward 5 ppm of ethanol gas. The morphology and structure of the different samples deposited on a silicon substrate were characterized by TEM, EDX, SEM, and Raman spectroscopy, and the results confirmed the presence of CNF decorated with gold. The influence of operating temperature (OT) and humidity were studied on the sensing devices. In the case of decorated samples with a high density of nanofibers, a less-strong cross-sensitivity was observed toward a variation in humidity and temperature. Full article

High-performance lab-scale perovskite solar cells often have a precious metal as the top electrode. However, there are drawbacks to using metal top electrodes on a large scale, such as inducing degradation processes, requiring a high-temperature deposition process under vacuum, and having low scalability. Recently many studies have shown the potentials of using a carbon electrode because of its conductivity, flexibility, low cost, and ease of fabrication. This review article presents an overview of using carbon materials to replace the top electrode in perovskite photovoltaics. We discuss various fabrication techniques, various carbon-based device structures, and the advantages of using carbon materials. A collection of research works on device performance, large-scale fabrication, and device stability is presented. As a result, this review offers insight into the future of large-scale flexible solar cells. Full article
