Abstract:
A direct-write method for depositing a polarized material onto a target surface, said method comprising the following steps:(1) forming a solution of a material capable of being polarized using a polarization solvent which can be removed by evaporation to provide a crystalline or amorphous polarized material which is substantially free of mechanically-induced orientation; (2) operating dispensing means to discharge and deposit said solution onto said target surface substantially point by point and at least partially removing said solvent from the deposited solution to form a thin layer of substantially solidified material of a predetermined pattern; and (3) during said solvent-removing step, subjecting the deposited solution to a DC electric field for poling until substantial polarization is attained to form said polarized material.
