4Pi microscopy of quantum dot-labeled cellular structures.
The most prominent restrictions of fluorescence microscopy are the limited resolution and the finite signal. Established conventional, confocal, and multiphoton microscopes resolve at best approximately 200nm in the focal plane and only 500nm in depth. Additionally, organic fluorophores and fluorescent proteins are bleached after 10(4)-10(5) excitation cycles. To overcome these restrictions, we...
متن کاملExploring and Exploiting Quantum-Dot Cellular Automata
The Full Adders (FAs) constitute the essential elements of digital systems, in a sense that they affect the circuit parameters of such systems. With respect to the MOSFET restrictions, its replacement by new devices and technologies is inevitable. QCA is one of the accomplishments in nanotechnology nominated as the candidate for MOSFET replacement. In this article 4 new layouts are presente...
متن کاملDesign of Optimized Quantum-dot Cellular Automata RS Flip Flops
Complementary metal-oxide semiconductor (CMOS) technology has been the industry standard to implement Very Large Scale Integrated (VLSI) devices for the last two decades. Due to the consequences of miniaturization of such devices (i.e. increasing switching speeds, increasing complexity and decreasing power consumption), it is essential to replace them with a new technology. Quantum-dot c...
متن کاملDesigning Cellular Automata Structures using Quantum-dot Cellular Automata
Quantum-dot Cellular Automata (QCA) is a promising, emerging nanotechnology based on single electron effects in quantum dots and molecules. While many logic implementations based on QCA devices have been proposed in literature [6, 7, 8], the inherent cellular structure of QCA cells make it a natural candidate for Cellular Automata (CA) implementation. CA offers regularity and modularity to the ...
