Sample 1B
- 6/13/2012 Spin photoresist and bake at 115 C for 1 minute to protect sample from debris during laser cut
Sample 1D
- 6/5/2012 Raman measurements
Sample 1D raman.xlsx
Raman measurements indicate that laser melted layer is single crystal. Main LO peak is located at about 530 cm-1, which would indicate compressive strain of about 1.5%.
