Special Issue Information

Dear Colleagues,

Two-dimensional (2D) materials have attracted tremendous research interest due to their unique optical, electronic, thermal, and mechanical properties. Two-dimensional materials comprise a large family with a very broad range of properties that can be easily altered by various physical, chemical, and heterostructuring strategies, which opens unprecedented opportunities for various kinds of novel device applications such as in field-effect transistors, memory, sensors, ultrasensitive photodetectors, logic electronic/optoelectronics devices, spintronic devices, and so on, which are difficult to construct using conventional bulk materials. Intensive research into 2D materials is expected to lead to the discovery of more functional, economical, and sustainable novel materials and devices with enhanced properties that will significantly benefit industries and society at large.

This Special Issue aims to present original, state-of-the-art articles on physics, devices, mechanisms, fabrication technologies, and applications involving 2D materials, including theoretical, numerical, and experimental studies. We welcome both original research and review articles.

Topics of interest include, but are not limited to:

  • Synthesis, fabrication, characterization, and properties of 2D materials.
  • Device physics and integration of 2D materials.
  • Light–matter interactions involving 2D materials.
  • Spectroscopy and imaging involving 2D materials.
  • Energy storage applications using 2D materials.
  • Wearable devices containing 2D materials.
  • Biochemical sensors containing 2D materials.
  • Bound states in the continuum in nanostructures containing 2D materials.
  • Quantum technology involving 2D materials.
  • Machine learning methods involving 2D materials.

In this article, the effects of high-energy proton irradiation on top-gate graphene field-effect transistors (GFETs) were investigated by using 20 MeV protons. The basic electrical parameters of the top-gate GFETs were measured before and after proton irradiation with a fluence of 1 × 1011 p/cm2 and 5 × 1011 p/cm2, respectively. Decreased saturation current, increased Dirac sheet resistance, and negative drift in the Dirac voltage in response to proton irradiation were observed. According to the transfer characteristic curves, it was found that the carrier mobility was reduced after proton irradiation. The analysis suggests that proton irradiation generates a large net positive charge in the gate oxide layer, which induces a negative drift in the Dirac voltage. Introducing defects and increased impurities at the gate oxide/graphene interface after proton irradiation resulted in enhanced Coulomb scattering and reduced mobility of the carriers, which in turn affects the Dirac sheet resistance and saturation current. After annealing at room temperature, the electrical characteristics of the devices were partially restored. The results of the technical computer-aided design (TCAD) simulation indicate that the reduction in carrier mobility is the main reason for the degradation of the electrical performance of the device. Monte Carlo simulations were conducted to determine the ionization and nonionization energy losses induced by proton incidence in top-gate GFET devices. The simulation data show that the ionization energy loss is the primary cause of the degradation of the electrical performance. Full article
