Applications of Monolayer Graphene on SiO₂/Si Substrate

Monolayer Graphene on SiO₂/Si substrate is widely used in advanced research and commercial development thanks to its well-defined, high-quality interface and compatibility with standard semiconductor fabrication processes. Here are key application areas:


1. Nanoelectronics
Serves as a fundamental platform for the fabrication and testing of nanoscale transistors, logic devices, and high-speed integrated circuits.

2. Field Effect Transistors (FETs)
Ideal for fabricating graphene-based FETs due to its atomically thin and conductive nature combined with insulating SiO₂.

3. Quantum Devices
Used in the development of quantum Hall effect devices, single-electron transistors, and other quantum electronic structures.

4. Photodetectors and Optoelectronics
Acts as an ultra-thin, transparent conductor and light-sensitive layer in graphene photodetectors and optical modulators.

5. Material Characterization
Extensively used for Raman spectroscopy, AFM, SEM, and other surface-sensitive measurements thanks to its stable and flat platform.

6. Biosensors
Functionalized graphene surfaces on SiO₂ substrates enable high-sensitivity detection of biomolecules in medical diagnostics.

7. Spintronics
Facilitates experiments involving spin transport and magnetoresistance, essential in spintronic device research.

8. Flexible Electronics Prototyping
Although rigid, the platform helps develop and characterize flexible circuit designs before they are transferred to polymer substrates.

9. Transparent Conductors
Used in studies to replace ITO in displays and touchscreens by evaluating sheet resistance and transparency on this stable substrate.

10. Educational and R&D Use
Universities and research institutes use it for hands-on graphene device prototyping and material science education.
