A massive two dimensional Dirac particle in a random electrostatic potential is considered. For a ribbon geometry (width << length), the Lyapunov exponent is calculated as a function of ribbon width, for several energies and disorder strengths. Intriguingly, an attempt to demonstrate one parameter scaling is only partially successful.
