What is the popular surface defect of diamond? I saw in some papers saying about hydrogenated and oxygenated surface diamond, but these are theoretical. Can you recommend me to any experimental sources of these?
Thank you so much!
Hi everyone!How can How can i explain the Raman spectra of carbon material when D peak exists, while 2D peak does not. Could there be a reverse case when in Raman spectra we observe the overtone...

We study detonation nanodiamond by RS. Samples were recieved in form of powder. Then we press this powder under high pressure 8GPa and T=1800C and got compact detonation nanodiamonds, that then...
