Special Issue Information

Dear Colleagues,

Advanced functional composites and nanomaterials play a major role in dielectric and pyroelectric films for electronic device applications. These materials generate a temporary voltage when there is a change in temperature, which occurs due to the changes in the crystal structure.

Conventional materials exhibit poor dielectric properties and are costly in nature. Researchers are focusing on developing novel, functional composite materials and nanofilms which offer good dielectric properties at a lesser cost. The multifunctional composites pave the way to use these advanced materials in newer-generation electronic devices.

We invite researchers to submit their research papers or review articles to this Special Issue, “Frontiers in Dielectric and Pyroelectric Films for Electronic Device Applications”. This Special Issue will help industries to use advanced materials in electronic devices. This also will motivate young researchers and budding engineers to understand the various materials used in electronic devices and help them to develop their work in the field. Research areas may include (but are not limited to) the following:

  • Synthesis and characterization of dielectric and pyroelectric films.
  • Influence of coating materials and coating thickness on dielectric properties.
  • Advanced manufacturing methods to prepare nanofilms.
  • Dynamic characteristics of materials on the surfaces.
  • Voltage and charge accumulation on electrode surfaces.

While charge transport in the horizontal plane of graphene has been widely studied, there is only limited understanding about the transport across a stack of films that include graphene sheets. In this report, a model of a metal–graphene–metal stack was produced and investigated via detailed analysis of experimental dependences of electrical current on applied external voltage. Scanning probe microscopy (SPM) was used to measure the dependences of the local tunneling current on the voltage under fixed compressing force. The SPM platinum probe produced the compressing force on gold-supported graphene in the metal–graphene–metal system. The experimental results were explained by a model that included the pinning of the Fermi level of graphene to platinum and the related changes in the parameters of the potential barrier for the electron flow. It was demonstrated that low-voltage and high-voltage intervals can be identified in the charge transport across the metal–graphene–metal stack. In the high-voltage interval (approximately > |±0.7| V in the tested stack), the history of the current measurement was detected due to the charge accumulation. In the low-voltage interval, the current was determined by the electronic states near the Fermi level. In this interval, the graphene layer can function as a blocking gate for the electron transport in the metal–graphene–metal system. Full article

Lightweight and flexible electronics have recently emerged at the forefront of optoelectronic applications. In this regard, graphene electrodes enable opportunities for new photodiode devices. In this paper, we formulated and tested graphene ink using the standard inkjet printing technique. It was shown that the maximum conductivity of ink was achieved for 14 print passes of the graphene layer. Moreover, we deposited Molybdenum Disulfide (MoS2) ink in the same pattern and used it as an active layer. We put MoS2 ink on an Indium-Tin-Oxide (ITO) glass substrate and then deposited graphene ink as a top electrode to fabricate an ITO/MoS2/graphene device. The fabricated device showed good rectification behavior and high ON/OFF switching behavior with a max photocurrent of 15 µA at +2 V. The technique thus paves the way for low-cost, low-temperature processing of electronics and one-step fabrication. Full article

The buckling behavior of graphene on soft films has been extensively studied. However, to avoid graphene fracture, most studies focus only on the primary buckling behavior induced by tiny compression. Here, the buckling behavior of monolayer, three-layer, and four-layer graphene on soft films is systematically studied in the experiment under large compression. The cross-sections of buckling patterns in these few-layer graphenes are provided, which depend on focused ion beam (FIB) technology. More significantly, the moduli of few-layer graphene are calculated based on the buckling behavior. We demonstrate that the modulus, 1.12621 TPa, is independent of the number of graphene layers if the number is less than four. Our investigations are crucial for the application of two-dimensional (2D) materials into flexible hybrid electronics, bionics, and various other stiff/soft bilayer systems. Full article
