Proton-triggered switch based on a molecular transistor with edge-on gate

Flicking the switch on a molecular gate.

T he use of external stimuli to manipulate the properties of well-defined materials may find applications in ondemand drug delivery, separation of molecules, sensing, smart coatings, or artificial tissues (1). Most of these applications rely on changes in the shape, stiffness, pore size, or other properties of soft materials in response to external pressure, temperature changes, or electric or ...

A nanoscale transistor based on gate-induced stochastic transitions

A nanoscale device consisting of a metal nanowire, a dielectric, and a gate is proposed. A combination of quantum and thermal stochastic effects enable the device to have multiple functionalities, serving alternately as a transistor, a variable resistor, or a simple resistive element with I −V characteristics that can switch between ohmic and non-ohmic. By manipulating the gate voltage, stochas...

A surface-anchored molecular four-level conductance switch based on single proton transfer.

The development of a variety of nanoscale applications requires the fabrication and control of atomic or molecular switches that can be reversibly operated by light, a short-range force, electric current or other external stimuli. For such molecules to be used as electronic components, they should be directly coupled to a metallic support and the switching unit should be easily connected to oth...

Field-effect transistor on SrTiO3 with sputtered Al2O3 gate insulator

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
