A novel method for the reduction of subthreshold slope below the room-temperature Boltzmann limit of 60 mV/dec for a field-effect transistor based on negative differential capacitance is proposed. This effect uses electric field induced electrostriction of a piezoelectric gate barrier of the transistor. The mechanism amplifies the internal surface potential over the applied gate voltage. This i...
The single channel junction field-effect transistor (JFET) is probably the simplest transistor available. As shown in the schematics below (Figure 6.13 in your text) for the n-channel JFET (left) and the p-channel JFET (right), these devices are simply an area of doped silicon with two diffusions of the opposite doping. Please be aware that the schematics presented are for illustrative purposes...
Recent developments towards future polymer electronics are aimed at different applications as organic displays, complementary circuits, and all-polymer integrated circuits [1-3]. Basic devices are organic field-effect transistors (OFET, cross section in Figs.2 and 3) with an active layer made from an organic material. Until now the achieved performance of OFET's is not sufficient for envisaged ...
The piezoelectronic transistor (PET) has been proposed as a transduction device not subject to the voltage limits of field-effect transistors. The PET transduces voltage to stress, activating a facile insulator-metal transition, thereby achieving multigigahertz switching speeds, as predicted by modeling, at lower power than the comparable generation field effect transistor (FET). Here, the fabr...
We give a detailed discussion of the quantum interference effect transistor (QuIET), a proposed device which exploits the interference between electron paths through aromatic molecules to modulate the current flow. In the off state, perfect destructive interference stemming from the molecular symmetry blocks the current, while in the on state, the current is allowed to flow by locally introduci...
We propose a spin-field-effect transistor based on spin-orbit coupling of both the Rashba and the Dresselhaus types. Different from earlier proposals, spin transport through our device is tolerant against spin-independent scattering processes. Hence the requirement of strictly ballistic transport can be relaxed. This follows from a unique interplay between the Dresselhaus and the Rashba couplin...
Graphene, after its first production in 2004 have received lots of attentions from researchers because of its unique properties. High mobility, high sensitivity, high selectivity and high surface area make graphene excellent choice for bio application. One of promising graphene base device that has amazingly high sensitivity is graphene field-effect transistor (GFET). This review selectively su...
The continuous scaling down of feature size in Silicon technology has resulted in several technological and fundamental hindrances. The researchers started to look for new nanoscale devices those can replace CMOS transistors in digital circuits. The nanowire transistor, FinFET, Carbon Nanotube field effect transistor (CNFET), tunnel field effect transistor (TFET), and single electron transistor...
This issue of the IBM journal describes recent advances in the field of nanoscience, with an emphasis on cathode lens-based microscopy methods, including LEEM (low-energy electron microscopy), PEEM (photoemission electron microscopy), and other related analytical approaches. Papers highlight scientific advances and instrumental developments on topics that include thin films, organic films, surf...
