The interplay between the use of random matrix theory and the semiclassical approach to describe conductance tluctuations in the ballistic regime is discussed. In order to understand the universal behavior as well as the correct physical scalings of conductance correlators one needs both theories. I
Experimental results of the CT 2. peak between adjacent IQHE states are analyzed with respect to temperature and frequency scaling. Universal behaviour (AB cx TK, K M 0.4) is observed when effects of individual impurities near the 2DEG are negligible, IC FZ 0.2 is observed for peaks with unresolved
