Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your papers to this Special Issue on “Actual Problems of Solid-State Physics: Nanomaterials and Nanotechnologies 2.0” which is the second volume of our previous Special Issue “Actual Problems of Solid State Physics: Nanomaterials and Nanotechnologies” (https://www.mdpi.com/journal/nanomaterials/special_issues/nano_solid_state_physics) in Nanomaterials. Results describing all aspects of low-dimensional functional materials synthesis and investigations are welcome. It is widely known that functional nanomaterials with controllable properties are attracting an increasing amount of attention today. This Special Issue is associated with the X Anniversary International Scientific Conference “Actual Problems of Solid-State Physics-2023” that will be held at the Scientific-Practical Materials Research Centre of National Academy of Sciences of Belarus (Minsk, Belarus) on May 2023. This will be a great scientific event in the field of condensed matter physics for nanomaterials development. However, anyone may contribute to this Special Issue (not only conference participants).

This Special Issue will focus on:

  • Physical and chemical technologies for nanomaterials production and modification;
  • Applications of functional nanomaterials;
  • Theory and modeling in the field of nanomaterials;
  • Multidisciplinary applications of nanomaterials.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Modern approaches to nanomaterials production and modification;
  • Strong correlation between chemical composition, size factor, and properties;
  • Novel composites based on nanomaterials;
  • Any application of nanomaterials.

We look forward to receiving your contributions.

2H MoTe2 (molybdenum ditelluride) has generated significant interest because of its superconducting, nonvolatile memory, and semiconducting of new materials, and it has a large range of electrical properties. The combination of transition metal dichalcogenides (TMDCs) and two dimensional (2D) materials like hexagonal boron nitride (h-BN) in lateral heterostructures offers a unique platform for designing and engineering novel electronic devices. We report the fabrication of highly conductive interfaces in crystalline ionic liquid-gated (ILG) field-effect transistors (FETs) consisting of a few layers of MoTe2/h-BN heterojunctions. In our initial exploration of tellurium-based semiconducting TMDs, we directed our attention to MoTe2 crystals with thicknesses exceeding 12 nm. Our primary focus centered on investigating the transport characteristics and quantitatively assessing the surface interface heterostructure. Our transconductance (gm) measurements indicate that the very efficient carrier modulation with an ILG FET is two times larger than standard back gating, and it demonstrates unipolarity of the device. The ILG FET exhibited highly unipolar p-type behavior with a high on/off ratio, and it significantly increased the mobility in MoTe2/h-BN heterochannels, achieving improvement as one of the highest recorded mobility increments. Specifically, we observed hole and electron mobility values ranging from 345 cm2 V−1 s−1 to 285 cm2 V−1 s−1 at 80 K. We predict that our ability to observe the intrinsic, heterointerface conduction in the channels was due to a drastic reduction of the Schottky barriers, and electrostatic gating is suggested as a method for controlling the phase transitions in the few layers of TMDC FETs. Moreover, the simultaneous structural phase transitions throughout the sample, achieved through electrostatic doping control, presents new opportunities for developing phase change devices using atomically thin membranes.

Organic semiconductors (OSCs) have attracted considerable attention for many promising applications, such as organic light-emitting diodes (OLEDs), organic field-effect transistors (OFETs), and organic photovoltaics (OPVs). The present work introduced E143 food dye as a new nanostructured organic semiconductor that has several advantages, such as low cost, easy fabrication, biocompatibility, and unique physical properties. The material was characterized using a transmission electron microscope (TEM), Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), and optical absorption spectroscopy. The study of X-ray diffraction (XRD) showed that E143 dye has a monoclinic polycrystalline structure. Electrical and dielectric properties were performed by impedance spectroscopy at frequencies (20 Hz–1 MHz) in the temperature range (303–473 K). The values of interband transitions and activation energy recommended the application of E143 dye as a new organic semiconductor material with promising stability, especially in the range of hot climates such as KSA.
