Mechanically controllable break junction electrodes

  1. Jun 22, 2011 #1
    Hi all :)

    There are some questions troubling me concerning mechanically controllable break junction electrodes.
    Generally, what happens is the bridge between the electrodes is opened by bending. At a certain point the bridge is broken and the two sharp electrodes are formed. So, my questions are the following:
    How stable are those freshly formed electrodes at room temperature?
    I mean, are they stable enough to remain more or less in the same shape over hours or are they degrading continually due to brownian motion, gravitation?
    Is there any literature describing my questions?

    I appreciate very much any helpful answer :)
