Journal Article
Shenton, S. A., Cooke, M. D., Racz, Z., Balocco, C., & Wood, D. (2018). The Effect of Humidity on Microwave Characteristics of 2 Screen Printed Paper-Based Electronics. physica status solidi (a) – applications and materials science, 215(11), Article 1700689. https://doi.org/10.1002/pssa.201700689

This paper addresses one of the key issues in using paper electronics at microwave frequencies. As paper is hygroscopic, the varying moisture content can lead to differing dielectric and even conductive properties of paper electronics and must be tak...

A quantitative study of the spreading behavior of electron-beam-evaporated Al, Au, Cr, Ge, Pt, and Ti on oxidized Si substrates has been performed using translated stencil masks. At least two mechanisms are needed to account for the lateral spreading... Read More about Characterization and control of unconfined lateral diffusion under stencil masks.

Nanofabrication using nanotranslated stencil masks and lift off (2004)
Journal Article
Racz, Z., He, J., Srinivasan, S., Zhao, W., Seabaugh, A., Han, K., …Wolfe, J. (2004). Nanofabrication using nanotranslated stencil masks and lift off. Journal of Vacuum Science and Technology B, 22(1), 74-76. https://doi.org/10.1116/1.1637916

We propose and demonstrate a technique for forming nanometer-scale metal features based on evaporation onto a substrate through a stencil mask. In this work, the stencil mask is laterally translated by a piezoflexure stage, between evaporations of di... Read More about Nanofabrication using nanotranslated stencil masks and lift off.
