Fundamental Properties:
Graphene film transferred onto quartz substrates retains its electronic, optical, and mechanical properties, while benefiting from the thermal behavior, low electrical conductivity, and optical transparency of quartz. The PMMA-assisted transfer produces graphene films for photonic and sensing applications. Listed properties include: Electrical Properties: Electrical conductivity with carrier mobility above 10,000 cm²/V-s. Typical sheet resistance <=500 Ω/sq (monolayer) and <=100 Ω/sq (multilayer). Low Raman D/G ratio confirms minimal defect density after PMMA-assisted wet transfer.
Optical Transparency: Graphene on quartz transmits ~97.7% of visible light and supports use in transparent and optoelectronic devices.
Mechanical Properties: Tensile strength ~130 GPa; the film is flexible.
Thermal Properties: Thermal conductivity of graphene combined with the heat resistance of quartz, applicable for high-temperature applications.

Applications:
Optoelectronics: Applicable for transparent conductive films in photonic devices, displays, and sensors, leveraging the optical transparency of quartz.
Electronics: Used in circuits and sensors, where the quartz substrate has insulating properties for device fabrication.
Sensors: Graphene on quartz is sensitive to gases, chemicals, and biological molecules, supporting environmental and diagnostic applications. Energy Applications: Utilized in transparent electrodes for energy storage devices, such as supercapacitors and batteries, where the quartz substrate provides thermal durability. Photonics and Quantum Applications: Quartz’s optical clarity and low-loss properties support graphene-based photonic and quantum devices.
