Special Issue Information

Dear Colleagues,

Two-dimensional materials (graphene, MoS2, Black Phosphorus et.) in combination with nano-fabrications can enable high performance sensors or novel sensors with new functionalities, opening a wide range of applications.

Two-dimensional materials can be the building blocks for various types of sensors, such as photodetectors, strain/pressure sensors, gas sensors, etc. Two-dimensional-based sensors can also be enlarged by creating two-dimensional heterostructures. Two-dimensional heterostructures can be produced by combining 2D with 3D/2D/1D/0D structures. This Special Issue aims to introduce two-dimensional materials in combination with nano-fabrications. Topics in general include, but are not limited, to:

  • Two-dimensional materials/heterostructures-based sensors: 2D material growth, transfer, fabrication, device prototype and demo;
  • Two-dimensional materials/heterostructures as photodetectors;
  • Graphene or other 2D materials-based strain/pressure sensor with high sensitivity;
  • Two-dimensional materials as bio-sensors;
  • Two-dimensional materials for acoustic or thermal sensing applications.

Charge-coupled devices (CCD) allow imaging by photodetection, charge integration, and serial transfer of the stored charge packets from multiple pixels to the readout node. The functionality of CCD can be extended to the non-destructive and in-situ readout of the integrated charges by replacing metallic electrodes with graphene in the metal-oxide-semiconductors (MOS) structure of a CCD pixel. The electrostatic capacitive coupling of graphene with the substrate allows the Fermi level tuning that reflects the integrated charge density in the depletion well. This work demonstrates the in-situ monitoring of the serial charge transfer and interpixel transfer losses in a reciprocating manner between two adjacent Gr-Si CCD pixels by benefitting the electrostatic and gate-to-gate couplings. We achieved the maximum charge transfer efficiency (CTE) of 92.4%, which is mainly decided by the inter-pixel distance, phase clock amplitudes, switching slopes, and density of surface defects. The discussion on overcoming transfer losses and improving CTE by realizing a graphene-electron multiplication CCD is also presented. The proof of the concept of the in-situ readout of the out-of-plane avalanche in a single Gr-Si CCD pixel is also demonstrated, which can amplify the photo packet in a pre-transfer manner.
