Nano-transistors Sensitive to Vibrations in a Single Molecule
... Molecular Transistors
Molecular devices might enable the
manipulation of single electrons on
the smallest possible device length
scales. A cross disciplinary group at
Cornell has demonstrated for the
first time a transistor device that
reaches the ultimate limit in which
an electron hops on and off ...

Hund’s Rule states that each orbital will be filled singly
Build by adding the required number of protons
before pairing begins. The singly filled orbitals will have
(the atomic number) and neutrons (the mass of the atom)
... 5) Using principles of chemical bonding and molecular geometry explain each of
the following observations. Lewis electron-dot diagrams and sketches of
molecules may be helpful as part of your explanations. For each observation
your answer must include references to both substances.

... What is a chemical reaction?
• A chemical reaction is a chemical change
where chemical substances (called
reactants) react to give new chemical
substances (called products).
– The combustion of hydrogen in oxygen is a
chemical reaction which gives water.
• Hydrogen and Oxygen are the reac ...
Molecular scale electronics
Molecular scale electronics, also called single molecule electronics, is a branch of nanotechnology that uses single molecules, or nanoscale collections of single molecules, as electronic components. Because single molecules constitute the smallest stable structures imaginable this miniaturization is the ultimate goal for shrinking electrical circuits.The field is often referred to as simply ""molecular electronics"", but this term is also used to refer to the distantly related field of conductive polymers and organic electronics, which uses the properties of molecules to affect the bulk properties of a material. A nomenclature distinction has been suggested so that molecular materials for electronics refers to this latter field of bulk applications, while molecular scale electronics refers to the nanoscale single-molecule applications discussed here.
