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…

Mechanism of recrystallization process in epitaxial GaN under dynamic stress field - Atomistic origin of planar defect formation
C. R. Das, S. Dhara, H. C. Hsu +6
The mechanism of recrystallization in epitaxial (1000) GaN film, introduced by indentation technique, is probed by lattice dynamic studies using Raman spectroscopy. The recrystalli…

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…
