| Abstract: | Asymptotic solutions for the Montroll-Weiss continuous-time random walk that are appropriate to the conduction of carriers through a resistive medium are utilized to show that, when carrier drift occurs by virtue of an applied electric field, a 1/f type of spectral density may be exhibited in the current noise. When the applied field is removed the spectral density is given by Nyquist's theorem. |
