Modulator devices are selectably adjustable between at least two states, wherein the transmission andor reflection of particular wavelengths of light are modified. Further, and the cap layer is formed at a crystal growth rate which is faster than the crystal growth rate of the well layer and removing the cap layer using a thermal cracking process during the temperature ramp up associated with the formation of the next group III nitride compound semiconductor layer. The hydrophilic polymer has quick tack when exposed to a hydrophilic solvent, such as water or other aqueous solvent, while the hydrophobic polymer provides strong adhesion to a paper or polymeric substrate.
