Real time visualization of template directed colloidal self assembly
Colloidal spheres play an important role as building blocks to fabricate basic photonic materials and lithographic masks, as they can self assemble into close packed 2D and 3D periodic arrays. In order to obtain more complex structures, patterned substrates have been used to direct the colloidal cry...
