Raman application note: Polarizer and 2D Material--InS


Polarizer and 2D Material--InS


Model: RAMaker 532
Laser wavelength: 532 nm
Laser power: 5 mW
Spot size: 5 um
Polarizer: parallel and perpendicular to the a axis of InS crystal


Analysis:

  1. Unpolarized: Five vibration modes 141, 164, 180, 245, and 290 cm-1 can be simultaneously detected.
  2. The 141, 161, and 290 cm-1 peaks are enhanced in the the E ll a-axis polarization with Z(XX)Z' configuration.
  3. The 180 and 245 cm-1 peaks are dominant in Z(XY)Z' spectrum.
