Nanoelectronics and nanomirror memory
Nanoelectronics refer to the use of nanotechnology on electronic components, especially transistors. .nanoelectronics often refer to transistor devices that are so small that inter-atomic interactions and quantum mechanical properties need to be studied extensively. hybrid molecular/semiconductor electronics, one dimensional nanotubes/nanowires, or advanced molecular electronics are the present candidates that fall in the nanoelectronic component category. Nanoelectronics holds the promise of making computer processors more powerful than are possible with conventional semiconductor fabrication techniques.The use of nanolithography, and the use of nanomaterials such as nanowires or small molecules in place of traditional CMOS components are set to change the computer scenario. FETs have been made using both semiconducting carbon nanotubes [9] and with heterostructured semiconductor nanowires.
The nanoelectronic memory device has the potential to increase storage capacity of memory by two fold without increase in the number of bits needed. Current-Voltage (I-V) characteristic of benzene ring molecule provides the scope of applying tri-stable logic principle using benzene ring molecule as special switching device.With the use of this principle, it will be possible to store negative numbers in memory or registers without need of special sign bit and without need of a special coding scheme. They can also be used in the elementary binary digital logic blocks like AND, OR, etc and logic blocks like ADD and SUBTRACT units using benzene molecules as basic tri-stable switching device and resistors in combination. A higher magnitude of current will be observed in the larger molecules for same voltage swing without major change in the qualitative behavior.

Nano Mirrors: A silicon device with thousands of slats of tiny mirrors lined up to resemble a jalousie . a device that uses nano mirrors to diffract X-ray and extreme ultraviolet range beams without the energy absorption that typically occurs with X-ray diffraction gratings. The silicon slats are as thin as 35 nanometers the size of some of the smallest computer chip transistors and wires under commercial development. The thousands of long, thin slats are spaced about 150 nanometers apart . plasma physics to the life and environmental sciences. are expected to benefit from the nano-mirror technology.
