Spin-related electronic pathway through single molecule on Au(111)

Spin-polarized transport through single-molecule magnet Mn6 complexes.

The coherent transport properties of a device, constructed by sandwiching a Mn6 single-molecule magnet between two gold surfaces, are studied theoretically by using the non-equilibrium Green's function approach combined with density functional theory. Two spin states of such Mn6 complexes are explored, namely the ferromagnetically coupled configuration of the six Mn(III) cations, leading to the...

Single molecule electronic devices.

Single molecule electronic devices in which individual molecules are utilized as active electronic components constitute a promising approach for the ultimate miniaturization and integration of electronic devices in nanotechnology through the bottom-up strategy. Thus, the ability to understand, control, and exploit charge transport at the level of single molecules has become a long-standing des...

Electronic transport in single-molecule magnets on metallic surfaces.

An electron transport is studied in the system that consists of a scanning tunneling microscopy, single-molecule magnet metal. Because of quantum tunneling of magnetization in a single-molecule magnet, linear response conductance exhibits stepwise behavior with increasing longitudinal field, and each step is maximized at a certain value of field sweeping speed. The conductance at each step osci...

Single-Molecule Electronic Measurements with Metal Electrodes

The process of transferring electrons from one metal electrode to another via an intervening molecule differs from electrochemically or optically-induced electron transfer in important ways. The simplest process of ballistic electron transport with no charge localization on the molecule (tunneling) should be easy to understand quantitatively, yet experimental reports and theoretical calculation...
