ab initio modeling of open systems: charge transfer, electron conduction, and molecular switching of a C_{60} device [PDF]

open access: yes, 2000
We present an {\it ab initio} analysis of electron conduction through a $C_{60}$ molecular device. Charge transfer from the device electrodes to the molecular region is found to play a crucial role in aligning the lowest unoccupied molecular orbital ...

Molecular Magnetic Switches

open access: yesCHIMIA, 2019
The design and synthesis of molecular switches is of growing importance considering the steep increase in the production of consumer electronics in the recent years. The function of these devices is based on binary electronic circuits and can be achieved by use of bistable magnetic materials.

Slow light in molecular aggregates nanofilms [PDF]

open access: yes, 2011
We study slow light performance of molecular aggregates arranged in nanofilms by means of coherent population oscillations (CPO). The molecular cooperative behavior inside the aggregate enhances the delay of input signals in the GHz range in comparison ...

Electrochemical control of quantum interference in anthraquinone-based molecular switches [PDF]

open access: yes, 2010
Using first-principles calculations we analyze the electronic transport properties of a recently proposed anthraquinone based electrochemical switch. Robust conductance on/off ratios of several orders of magnitude are observed due to destructive quantum ...

Silicon-based molecular switch junctions [PDF]

open access: yes, 2009
In contrast to the static operations of conventional semiconductor devices, the dynamic conformational freedom in molecular devices opens up the possibility of using molecules as new types of devices such as a molecular conformational switch or for ...

Mathematical model of a serine integrase-controlled toggle switch with a single input [PDF]

open access: yes, 2018
Dual-state genetic switches that can change their state in response to input signals can be used in synthetic biology to encode memory and control gene expression.

Negative differential electrical resistance of a rotational organic nanomotor

open access: yesBeilstein Journal of Nanotechnology, 2015
A robust, nanoelectromechanical switch is proposed based upon an asymmetric pendant moiety anchored to an organic backbone between two C60 fullerenes, which in turn are connected to gold electrodes.

Reset and switch protocols at Landauer limit in a graphene buckled ribbon

open access: yes, 2015
Heat produced during a reset operation is meant to show a fundamental bound known as Landauer limit, while simple switch operations have an expected minimum amount of produced heat equal to zero.

Electronic conduction in a three-terminal molecular transistor [PDF]

open access: yes, 2008
The electronic conduction of a novel, three-terminal molecular architecture, analogous to a heterojunction bipolar transistor is studied. In this architecture, two diode arms consisting of donor-acceptor molecular wires fuse through a ring, while a gate ...

Reversible molecular motional switch based on circular photoactive protein oligomers exhibits unexpected photo-induced contraction

open access: yesCell Reports Physical Science, 2021
Summary: Molecular switches alterable between two stable states by environmental stimuli, such as light and temperature, offer the potential for controlling biological functions. Here, we report a circular photoswitchable protein complex made of multiple
