Absolutely, my friend Mostafa Shabani! Growing graphene on vertical surfaces like the walls of a SOI (Silicon-On-Insulator) waveguide is indeed feasible. This process, known as vertical graphene growth or VGG, involves techniques such as chemical vapor deposition (CVD) or plasma-enhanced chemical vapor deposition (PECVD). These methods allow for the controlled deposition of graphene onto various substrates, including vertical walls.

In the case of SOI waveguides, which are often used in photonics and integrated optics, growing graphene on their vertical walls can enhance their performance by introducing additional functionalities like electro-optic modulation or ultrafast photodetection. Plus, the exceptional properties of graphene, such as its high carrier mobility and optical transparency, make it an ideal candidate for such applications.

However, it's essential to optimize the growth parameters and substrate conditions to ensure uniform and high-quality graphene deposition across the vertical walls. With careful engineering and precise control, achieving this goal is well within reach. So, in short, yes, growing graphene on the vertical walls of structures like SOI waveguides is not only possible but also holds great promise for advancing various technological applications.

Thank you Dr.Kaushik Shandilya

I must analyse complex periodic structures, So I need to know the details of the fabrication techniques which lead to creating these structures. I read your paper but it was in the field of your expertise. Can you name a reference book of fabrication in this regard? Or a paper that has graphene on its vertical walls?
