Negative differential resistance of porous silicon

IEEE Electron Device Letters, 2000
A porous silicon Al Schottky barrier diode shows differential negative resistance. The thin wires in porous silicon have much lower electron mobility than that of thick wires, due to electron surface scattering from space confinement. The energy of carriers in thick wires increases with applied bias.

Negative Differential Resistance in C60 Diodes

2009
Morphology studies and current-voltage (IV) measurements of C60 thin film diodes in the temperature range of 300–4.2 K are presented. For defined evaporation parameters orientation domains along the growth direction are demonstrated by cross section transmission electron microscopy.

New negative differential resistance effects in the negative resistance field-effect transistor

Journal of Applied Physics, 1989
We report two new effects of negative differential resistance in the modulation-doped AlGaAs/GaAs negative resistance field-effect transistor. Both effects are well controlled by a third electrode. Presence of a top n+ AlGaAs layer causes a hot-electron real-space transfer to this layer, and prevents the electron transfer to the collector.

Negative Differential Resistance (NDR) Measurements

1988
We present results on the observation of resonant tunneling negative differential resistance (NDR) through a GaAs/AlGaAs superlattice structure at room temperature and at 4.2 K made by molecular beam epitaxy. The conduction mechanism for the superlattice is miniband conduction and the entire structure behaves similarly to the normal two-barrier ...

Negative differential resistance at atomic contacts

Physical Review B, 1997
Negative differential resistance is found for a pair of electrodes each consisting of a single Al atom coupled to a flat metal surface, where the Al atom is separated from the surface by a ``spacer'' atom (Br). This behavior is seen when the Al atoms are at a short distance from one another, and disappears when the distance is decreased to the point at

Tunneling Negative Differential Resistance in a GSC

2013
This chapter describes the discovery of a wide NDR region in a graphite silicone composite (GSC) at low temperatures. Experimental and theoretical evidence is used to demonstrate that the NDR originates from a semi-metal to insulator transition of embedded bilayers in specifically orientated graphite nanoparticles. NDR has not been observed before in a
