A complete Raman mapping of phase transitions in Si under indentation
C. R. Das, H. C. Hsu, S. Dhara +7
Crystalline Si substrates are studied for pressure induced phase transformation under indentation at room temperature using Berkovich tip. Raman scattering study is used for the id…

Recrystallization of epitaxial GaN under indentation
S. Dhara, C. R. Das, H. C. Hsu +6
We report recrystallization of epitaxial (epi-) GaN(0001) film under indentation.Hardness value is measured close to 10 GPa, using a Berkovich indenter. Pop-in burst in the loading…
