Real-Time Drift Correction of a Focused Ion Beam Milling System

Freeman D., Luther-Davies B., Madden S., Australian National University, AU

We are working towards the fabrication of large periodic optical structures known as photonic crystals. A focused ion beam (FIB) is used to mill holes, which must be smooth and repeatable, with nm positional accuracy. [...]

A Robust Approach for Estimating Diffusion Constants from Concentration Data in Microchannel Mixers

Coelho C.P., Desai S., Freeman D., White J.K., Massachusetts Institute of Technology, US

In this paper we present a robust and geometry independent method for the estimation of diffusion coeffients of solutes from image data. Our diffusion coefficient estimation algorithm works in two steps. First, given the device [...]
