Abstract
A nanopost glass array contains up to 1012/cm2 of magnetizable nanoposts having diameter of 10-1000 nm that are straight and parallel to each other and are typically of a uniform diameter relative to each other and along the post length. The array is made using a reference electrode and a nanochannel glass template structure connected to each other electrically through an electrical source and both disposed in a plating solution. A magnetizable material is electroplated from the plating solution into the channels of the template structure.
Claims18
A process comprising the step of depositing from a plating solution a material into channels of a glass template to form an array containing up to 1012 of elongated structures per square centimeter having diameter of about 10 nm to micron size with aspect ratios of up to 10,000.
In a process for making a nanopost glass array from a nanochannel glass template containing up to 1012/cm2 of nanochannels having diameters of 10-1000 nm that are parallel to each other to within less than one degree and which channels are of a uniform diameter and have a uniform geometric placement to within 5 percent relative to each other and along the channel length, the channels are disposed perpendicularly between two faces of the template and the template being disposed in a plating solution and spaced from a counter electrode which is also disposed in the plating solution and electrically connected to the template across a voltage source, the process comprising the step of providing sufficient electromotive force in the plating solution to deposit a material from the plating solution into the template channels in less than 20 hours to form the nanopost glass array.
