Hi,
Myself Dr. Balakrishna Ananthoju. I am working on the synthesis of hexagonal boron nitride using rf-magnetron sputtering. I am using Boron nitride sputtering target. I have deposited the boron nitride on Sapphire substrates. My target is to get the hexagonal phase of the BN. After deposition I have done the Raman measurements and observed the peak at 1160 cm-1 (Laser wavelength 780 nm). But hexagonal BN case most of the reports show the Raman peak at 1366 cm-1. My query is can we consider this 1160 cm-1 peak for the confirmation of hexagonal BN phase. If not I would like to know what exactly is this peak? I have attached the Raman data for your reference.
I will be grateful for your kind help in this.
I am looking forward to hearing from you.
Sincerely,
Dr. Balakrishna Ananthoju
Dear Prof. Dibya P Rai,
Thank you very much for your reply. It would be great if you could suggest from DFT calculations comparison.
Much appreciate your valuable suggestion.
Regards,
Dr. Balakrishna Ananthoju
I am having same spectra but my process is CVD on copper. My peak is not too sharp. Still, don't whether its c-BN or doped h-BN.
Dear balakrishna ananthoju
Please read some of our research articles on Boronnitride nanotubes. We have detail experimental analysis including Raman. Both of your ( reported 1160 cm-1 and expected 1370 cm-1) peaks are reported and described . You can find out our boron nitride nonostructures related articles via link below:
