Scaling analysis of negative differential thermal resistance [PDF]

Physical Review E, 2014
Negative differential thermal resistance (NDTR) can be generated for any one-dimensional heat flow with a temperature-dependent thermal conductivity. In a system-independent scaling analysis, the general condition for the occurrence of NDTR is found to be an inequality with three scaling exponents: $n_{1}n_{2}

Tuning negative differential resistance in a molecular film [PDF]

Applied Physics Letters, 2005
We have observed variable negative differential resistance (NDR) in scanning tunneling spectroscopy measurements of a double layer of C60 molecules on a metallic surface. Minimum to maximum current ratios in the NDR region are tuned by changing the tunneling barrier width.

Negative differential resistance of electrons in graphene barrier [PDF]

Applied Physics Letters, 2007
The graphene is a native two-dimensional crystal material consisting of a single sheet of carbon atoms. In this unique one-atom-thick material, the electron transport is ballistic and is described by a quantum relativisticlike Dirac equation rather than by the Schrödinger equation.

Negative differential electrical resistance of a rotational organic nanomotor

Beilstein 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.

Spectral characteristics of initial and irradiated GaAsP LEDs [PDF]

Ядерна фізика та енергетика, 2021
The optical characteristics of the GaAs1-хPх output LEDs and LEDs irradiated with electrons with Е = 2 MeV, Ф = 1015 ÷ 1016 cm-2 were studied. The width of the band gap of the GaAs1-хPх (х = 0.45) solid solution was estimated. Its growth is caused by the

Modulation-induced negative differential resistance in bistable systems [PDF]

Physical Review Letters, 1987
This paper demonstrates that a wide range of driven, overdamped, nonlinear systems can exhibit negative differential resistance, where the equilibrium amplitude of oscillation decreases as the amplitude of the driving force increases. As an example, we examine the response of a parametrically driven bistable electronic circuit to both a dichotomous and
