Nanotechnology in Electronics and Electrical EngineeringReconfigurable Computing and Electronic Nanotechnology Free Full Downloads In thispaper we examine the opportunities brought about by recentprogress in electronic nanotechnology and describe the methods needed to harness themfor building a new computer architecture. In thisprocess we decompose some traditional abstractions, such as the transistor, intofine-gr ain pieces, such as signal restoration and input-output isolation. We also show how we can forgo the extreme reliability of CMOS circuits for low-cost chemical self-assembly at the expense of large manufacturing defect densities. We discuss advanced testing methods which can be used to recover perfect functionality fr om unreliableparts. We proceed to show how the molecular switch, the regularity of the circuits created by self-assembly and the high defect densities logically require the use of reconfigurable hardware as a basic building blockfor hardware design. We then capitalize on the convergence of compilation and hardware synthesis (which takes place when programming reconfigurable hardware) to propose the complete elimination of the instruction- set architecturefr om the system architecture, and the synthesis of asynchronous dataflow machines directly fr om high-level programming languages, such as C. We discuss in some detail a scalable compilation system thatperform this task. Overview of Nanoelectronic Devices This paper provides an overview of research developments toward nanometer-scale electronic switching devices for use in building ultra-densely integrated electronic computers. Specifically, two classes of alternatives to the field-effect transistor are considered: 1) quantum-effect and single-electron solid-state devicesand2)molecularelectronicdevices.Ataxonomy of devices in each class is provided,operationalprinciplesaredescribedand compared for the various types of devices, and the literature about eachissurveyed.This in format ion is presented in non mathematical terms intended for a general, technically interested readership. Nanorobots, NEMS, and Nanoassembly Nanorobotics encompasses the design, fabrication, and programming of robots with overall dimensions below a few micrometers, and the programmable assembly of nanoscale objects. Nanorobots are quintessential nanoelectromechanical systems (NEMS) and raise all the important issues that must be addressed in NEMS design: sensing, actuation, control, communications, power, and interfacing across spatial scales and between the organic/inorganic and biotic/abiotic realms. Nanorobots are expected to have revolutionary applications in such areas as environmental monitoring and health care. This paper begins by discussing nanorobot construction, which is still at an embryonic stage. The emphasis is on nanomachines, an area which has seen a spate of rapid progress over the last few years.NanoactuatorswillbeessentialcomponentsoffutureNEMS. The paper’s focus then changes to nanoassembly by manipulation with scanning probe microscopes (SPMs), which is a relatively well established process for prototyping nanosystems. Prototyping of nanodevices and systems is important for design validation, parameter optimization and sensitivity studies. Nanomanipulation also has applications in repair and modification of nanostructures built by other means. High-throughput SPM manipulation may be achieved by using multitip arrays. Experimental results are presented which show that interactive SPM manipulation can be used to accurately and reliably position molecular-sized components. These can then be linked by chem- ical or physical means to form subassemblies, which in turn can be further manipulated. Applications in building wires,single-electron transistors, and nanowaveguides are presented. Prospectus on Silicon Nanoelectronics.
