YAAVIK MATERIALS AND ACS MATERIALS PRESENTS CVD Graphene on SiO2 Substrate in India.

Product Detail

CAS No.: 7782-42-5 (graphene), 7631-86-9 (silicon dioxide), 7440-21-3 (silicon)

We are thrilled to be a part of the exciting research and innovation involving graphene. We are committed to providing a full range of outstanding graphene products, including these high-quality CVD Graphene sheets on SiO2 substrate. Our proven, proprietary method for CVD transfer of graphene onto P-type, 1-10 Ω·CM silicon dioxide substrate includes the following steps:

1. Growing monolayer graphene on copper foil
2. Depositing onto SiO2 via PMMA
3. Curing
4. Removing Cu by etching process
5. Washing PMMA/graphene in DI water
6. Redepositing PMMA/graphene onto silicon dioxide substrate followed by curing
7. Removing PMMA with acetone

The result is a superior product in every way.

• Our process allows us to create graphene sheets in various sizes, from 0.5 cm x 0.5 cm to 1” x 1”.
• Monolayer sheets or multilayer sheets are available: 1, 2, 3-5, or 6-8 layers.
• The thickness and quality of the films is precisely controlled using Raman spectroscopy.
• Graphene films are continuous with minimal holes and cracks.

CVD Graphene on SiO2 substrate is just one of many graphene products and services offered . Others include:

• Large size graphene on copper foil in sheets up to 30 cm x 20 cm
• Double or multilayer graphene sheets on various substrates
• Pretreated graphene coated in PMMA; with simple steps‚ you can easily transfer graphene to other substrates
• Graphical graphene customized according to graphics mask supplied by customers
• Customized services providing different floors‚ different sizes of graphene, various graphene transfer services, nitrogen-doped graphene, etc;

Graphene on silicon dioxide (300nm)/Si substrate (p-type, 1-10 Ω·cm) was prepared by the following steps:

1. Monolayer graphene grown on copper foil
2. Deposit PMMA and cure
3. Remove Cu by etching process
4. Wash PMMA/Graphene in DI water
5. Redeposit PMMA/Graphene onto silicon dioxide substrate and cure
6. Remove PMMA with acetone
