The thermal J‐V characteristic for a tunnel junction is derived in terms of a generalized theory. The resulting functional form of the equations is similar to that of Stratton; however, in the present formulation, the physical parameters of the junction appear explicitly, and their effect upon the thermal characteristic is readily appreciated. In Stratton's work, the physical constants appear in the integrand of integral that can be solved only numerically.The theory is applied to symmetric and asymmetric junctions. For the symmetric case, it is shown that, at a given temperature, the percentage change Ĵ in the high‐temperature thermal component of current from the low‐temperature value increases initially with increasing voltage bias up to a maximum peak, and thereafter decreases rapidly. The voltage bias at which the component of thermal current maxima occurs is equal to the interfacial barrier height and, as such, permits what is probably the most accurate method of barrier height determination.

Experimental studies on 1/f noise
TL;DR: Experimental studies on 1/f noise are reviewed with emphasis on experiments that may be decisive in finding the correct theoretical model for this type of noise as discussed by the authors. But the applicability of either theory turns out to be very limited.

Generalized Formula for the Electric Tunnel Effect between Similar Electrodes Separated by a Thin Insulating Film
TL;DR: In this article, a formula for the electric tunnel effect through a potential barrier of arbitrary shape existing in a thin insulating film was derived for a rectangular barrier with and without image forces, where the true image potential was considered and compared to the approximate parabolic solution derived by Holm and Kirschstein.

E. L. Murphy,R. H. Good +1 more
TL;DR: In this paper, a general expression for the emitted current as a function of field, temperature, and work function is set up in the form of a definite integral, and each type of emission is associated with a technique for approximating the integral and with a characteristic dependence on the three parameters.

Electric Tunnel Effect between Dissimilar Electrodes Separated by a Thin Insulating Film
TL;DR: In this article, the theory of the electric tunnel effect has been extended to asymmetric junctions, i.e., junctions having electrodes of different materials, and it is found that the J-V characteristic is polarity-dependent.

Tunneling of a Wave Packet
TL;DR: In this paper, the authors derived an analytic expression for the time spent by a particle tunneling through a potential barrier with constant average velocity, and showed that the resultant transmission time is positive, nonzero and in principle measurable.
