in this research chloroaiminium and copper phthalocyanine(clalpc and cupc)were purified twice, using entrained sublimitation techniques. ohmic contacts were made on the samples using the electrical properties of both (clalpc and cupc) were studied over a range of temperatures. the activation energies of these materials were measured using both forward and reverse current-voltage characteristic ...

studied. The experimentally obtained values of transport current exceed the normal phase minimum propagation current substantially. The current-voltage characteristics of the investigated samples have been studied. I t is shown that the relatively high value of the maximum transport current is attributed, under the given experimental conditions, to the behaviour of the current-voltage character...

By solving the Bogoliubov-de Gennes equation self-consistently in the presence of a non-equilibrium quasi-particle distribution, we compute the current-voltage characteristic of a phase coherent superconducting island with a tunnel barrier at one end. The results show significant structure, arising from the competition between scattering processes at the boundaries of the island and modificatio...

In its original form, the two-graph method allows only circuit components that are described by a v-i relationship of the admittance type (G, C, gm). In particular, it excludes resistors (expressed as resistance R rather ten conductance G), inductors and current-controlled current sources. Practising circuit designers often prefer to have symbolic analysis results expressed in terms of resistan...
