ABSTRACT

We demonstrate the fabrication of mesoscopic devices on aluminum thin film by using atomic force microscopic (AFM) electric field induced oxidation together with selective wet etching. The device structure being demonstrated is a percolating network consisting of conducting dots (70 nm in diameter) randomly distributed within an area of 1 x 1 f..Lm2• Details on how to fabricate the network structure and the making of electrical contacts to the device will be focused upon. Good agreement between the temperature-dependent resistivity and Hall coefficient measurements of an aluminum control sample we made and those reported in the literature for bulk aluminum warrants reliability of our sample fabrication technique.
