Mesoporous Thin Films

In this manuscript the preparation of highly ordered mesoporous cobalt films containing close packed arrays of spherical holes of uniform size was demonstrated by electrochemical deposition using the hexagonal liquid crystal template (H1-e Co). The template used was Brij®78 surfactant. Transmission electron microscopy (TEM), scanning electron microscopy (SEM), voltammetric methods, and low angle X-ray diffraction (XRD) were used to characterize the electrodeposited mesopores films. Cyclic voltammetry (CV) technique are used to show the mesoporous thin films are promising to be used as electrode materials of high - performance super capacitors.

Dimensional Errors

Arrays of SU-8 photoresist pillars (10 μm ×10 μm × 50 μm) on copper substrates were fabricated by X-ray lithography. The photoresist-coated substrates were irradiated by X-ray from a synchrotron source through patterned silver dots on a graphite mask. After the resist development, the chemically stable and mechanically hardened SU-8 pillars exhibited smooth vertical sidewalls and cross section with up to 10 % dimensional errors from the designated pattern. Cobalt of thickness ranging from 50 to 80 nm was then deposited on these patterned substrates by RF sputtering. These cobalt films on SU-8 pillars showed a lower in-plane magnetization than that of continuous cobalt films because of their smaller grain size. The measurement with out-of-plane magnetic field gave rise to a higher magnetization and this anisotropic behavior was observed only in cobalt-coated pillars.
