A new side-contacted field effect diode (S-FED) structure has been introduced as a modified S-FED, which is composed of a diode and planar double gate MOSFET. In this paper, drain current of modified and conventional S-FEDs were investigated in on-state and off-state. For the conventional S-FED, the potential barrier height between the source and the channel is observed to become larger and the flow of injected electrons is reduced. Thus, the drain current decreases in on-state. While in offstate, the potential barrier height and width become smaller in conventional S-FED and so the drain current is greater than that of modified structure. Mixed mode simulations were used to determine the performance of the proposed logic gates. We compared the operation of modified S-FED with that of conventional S-FED. Simulated power delay product (PDP) of the modified S-FED-based NOR, NAND, XOR gates were found to be about 416fJ, 408fJ and 336fJ, respectively, compared with 906fJ, 810fJ and 705fJ achievable with conventional S-FED logic gates.

The performance of a fish guiding device located just upstream a hydropower plant is scrutinized. The device is designed to redirect surface orientated down-stream migrating fish (smolts) away from the turbines towards a spillway that act as a relatively safe fishway. Particles are added up-stream the device and the fraction particles going to the spillway is measured. A two-frame Particle Tracking Velocimetry algorithm is used to derive the velocity field of the water. The experimental results are compared to simulations with CFD. If the smolts move passively as the particles used in the study the guiding device works very well and some modifications may optimize its performance. In-field Particle Tracking Velocimetry is a suitable technique for the current case and the results compare well with numerical simulations.

The electronic and vibrational atomic responses to external electric field (EF) are computed to detail intramolecular energy transfer in a proposed molecular nanoelectronic field-effect system. The parallel and perpendicular electronic and vibrational contributions to intramolecular energy transfer are computed using, respectively, quantum theory of atoms-in-molecule and an energy partitioning scheme based on normal modes vibrational analysis. The symmetrical and asymmetrical intramolecular energy transfers are interpreted, respectively, as Peltier-like and Joule-like effects and quantified in terms of appropriate coefficients. Dependencies of these coefficients on EF are investigated. In addition, a semiclassical temperature model is introduced to describe symmetrical and asymmetrical temperature distributions which are attributed, respectively, to the Joule-like and Peltier-like heatings. This procedure can be used to map out intramolecular energy distribution in molecular nanoelectronic systems.
