We intend to use the Si wafers as substrate for graphene. This graphene on Si substrate will be used as a photodetector. Please let me know if this description is enough. Thank you, Best, Bernat
The following wafer spec works great for your photodetector research!
Item 1113-DCTO/FGA: Silicon 100mm N/As (100) 0.001-0.005 ohm-cm SSP 500um with 2,850 angstroms Dry Chlorinated Thermal Oxide and forming gas anneal.
Never sacrifice a wafer again!
Just peal away the Graphene and reuse your expensive GaAs, InP, GaP wafers.
UniversityWafer, Inc. has teamed up with world renowned laboratories to offer a unique graphene metrology service that provides characterization and analysis on graphene materials.
Dozens of companies are producing various types of graphene materials, which causes much diversification and confusion. Our metrology service offers graphene producers the chance to obtain valuable test results and post-testing analysis and interpretation, that assist in proving viability and quality of production. In addition, displaying critical data to customers like the material characteristics and potential applications is key to successful marketing and sales activities.
