Electroluminescence in a rectifying graphene/InGaN junction

In situ characterization of a rectifying electrical junction.

Electrical synapses play significant roles in neural processing in invertebrate and vertebrate nervous systems. The view of electrical synapses as plain bidirectional intercellular channels represents a partial picture because rectifying electrical synapses expand the complexity in the communication capabilities of neurons. Rectification derives, mostly, from the sensitivity of electrical junct...

Electroluminescence from a single nanotube-molecule-nanotube junction.

The positioning of single molecules between nanoscale electrodes has allowed their use as functional units in electronic devices. Although the electrical transport in such devices has been widely explored, optical measurements have been restricted to the observation of electroluminescence from nanocrystals and nanoclusters and from molecules in a scanning tunnelling microscope setup. In this Le...

Thorough subcells diagnosis in a multi-junction solar cell via absolute electroluminescence-efficiency measurements

World-wide studies on multi-junction (tandem) solar cells have led to record-breaking improvements in conversion efficiencies year after year. To obtain detailed and proper feedback for solar-cell design and fabrication, it is necessary to establish standard methods for diagnosing subcells in fabricated tandem devices. Here, we propose a potential standard method to quantify the detailed subcel...

CFTR, a rectifying, non-rectifying anion channel?

Electroluminescence in Mylar Films

slowly or even stored at 95 °K for 8 or 16 hours 12. The ordering of this small part of the ice seems to be an almost spontaneous occurrence as the tempe­ rature is lowered to about 120 °K. A lowering of the activation energy for the movement of the defects in the neighbourhood of the dopant molecule could be the cause. It would mean that the area around a foreign molecule is quickly reorientat...
