Electric Field Induced Second Harmonic Generation in Vacuum Evaporated Disperse Red 1 films
We have observed the electric field induced second harmonic (EFISH) generation effect on vacuum deposited Disperse Red 1 (DR1) films using corona poling. There is no second harmonic generation (SHG) signal in the absence of the corona. Room temperature corona charging results in an SHG signal which appears and disappears almost instantaneously upon turning on and turning off the corona field respectively. Combined with earlier spectroscopic studies on molecular organization in vacuum deposited...[Show more]
