Dielectric and structural studies on sulphamic acid (SA) single crystal

Sulphamic acid single crystal of the size 14 × 8 × 6 mm3 has been grown by slow cooling solution growth method at 35.5 °C. Fermi resonance vibrations of N–S stretching and SO3 rocking have been observed from micro-Raman analysis. Different shapes of etch patterns have been observed for etchants like water, ethanol and HCl for different etching periods. The dielectric constant and dielectric loss have been measured for different frequencies at different temperatures.
