Welcome to the Arnold group homepage

Prof. Craig B. Arnold and his research group focus on materials processing and fabrication, with applications in energy, optoelelectronics, sensing and nanotechnology.

News and recent publications

• Laser-processed transparent electrodes

  

  J. A. Spechler and C. B. Arnold. Appl. Phys. A (2012) demonstrates a direct-write laser refining technique that lowers the macroscopic sheet resistance of transparent silver nanowire network electrodes by welding together nanowire-to-nanowire junctions.

• Battery charge storage efficiency effects

  

  E. Krieger and C. B. Arnold, J. Power Sources (2012) model the effects of undercharge and internal loss on the rate dependence of energy storage in batteries with implications for efficient operation of battery charging systems for variable power sources.

• Parallel nanopatterns on rough surfaces

  

  Y.-C. Tsai et. al., IOP Nanotech. (2012) generates precise parallel nanofeatures on rough surfaces with vertical steps more than 1.5 μm using OTAN. A Brownian motion model is used to describe and predict the lateral positional accuracy of the system.

• Ultrastable nanostructured polymer glasses

  

  Y. Guo et. al., Nature Materials (2012) forms ultrastable nanostructured glassy polymer films with superior properties (lower density, enhanced stability, higher T_g) compared to standard PMMA using matrix-assisted pulsed laser evaporation (MAPLE).
