A simple method to measure electrical conductivity of conducting organic films has been described. A setup, based on four-probe technique, is specifically designed and fabricated for nondestructive electrical conductivity measurements of freestanding thin films. The current-voltage and temperature dependent characteristics of thin films of polyethylenedioxythiophene and polypyrrole and thick wafers of germanium have been used to test the setup. The results obtained are highly reproducible and are in good agreement with the reported values in the literature, employing different techniques.

    The effect of collector lateral scaling on the performance of 300 GHz-level SiGe HBTs is investigated. Peak fT and fmax exhibited an initial improvement followed by a degradation with decreasing collector width. Possible causes behind the observed trend are discussed in terms of RC delay and the...

    Resistivity of metastable amorphous Ge2Sb2Te5 (GST) measured at device level show an exponential decline with temperature matching with the steady-state thin-film resistivity measured at 858 K (melting temperature). This suggests that the free carrier activation mechanisms form a continuum in a...
