Special Issue Information

Dear Colleagues,

This Special Issue of Materials is dedicated to low-dimensional materials for optoelectronics and photovoltaics. Low-dimensional science offers tremendous opportunities compared to bulk materials. An interdisciplinary community of chemists, physicists, and materials scientists focusing on atomically thin-layer materials, confined structures in zero, one, or two dimensions, and interfaces has made significant efforts and demonstrated that novel optoelectronic and photovoltaic processes can be developed and applied to specific applications. Indeed, there have been important advances in the photo- and micro-electronic industries due to materials that occur naturally, are synthetically designed, and are artificially engineered at low dimensions.

For this Special Issue, we invite the submission of original research articles and reviews on fundamental and applied research focused on low-dimensional materials for optoelectronics and photovoltaics, including, but not limited to, the following:

  • Semiconductor and heterostructure optoelectronics and photovoltaics;
  • Mesoscopic phenomena in nanostructures;
  • Plasmonic and phononic systems;
  • Energy conversion and energy-harvesting processes;
  • Nonlinear optoelectronic processes;
  • Optoelectronics of 2D materials and their heterostructures;
  • Carrier dynamics in organic materials and interfaces;
  • Ultra-fast optical phenomena at low dimensions;
  • Optoelectronics of nanowires and quantum dots;
  • Flexible optoelectronics and photovoltaics.

Research contributions and review articles highlighting recent progress in these fields are all welcome.

Nonlinear photocurrents (NPs) are electrical currents expected to be measured at the electrodes of a device consisting of an active area, sensitive to light, with a higher-order in-electric field where light-impinging geometry (LIG) is the determining factor in the experimental observation. Although the phenomenology of this light–matter interaction is clear for light directed on a lateral device plane with well-defined azimuthal and incidence angles, as well as light polarization angle, it can be quite complicated for a vertical device structure and reconsideration of the expected NP contributions is necessary in the latter case. In this study, we used a visual approach to describe the LIG for vertical device structures using a specific example of a photodiode, and showed that these angles must be redefined, namely, the interchangeability of azimuthal and incidence angles. The influence of device geometry-dependent optical illumination is reflected on the behavior of NP; therefore, the NPs that are known to be forbidden in certain LIGs can be allowed and vice versa. These results pave the way for the utilization of NPs in flexible optoelectronic applications. Full article
