Example Sentences

Round, an English wireless expert working as an engineer for the Marconi Wireless and Telegraph Co. in New Jersey, discovered electroluminescence in a solid-state diode — light that was not visible to the human eye, only via instruments.

Such sensitivity of the electroluminescence enhancement to charge imbalance is consistent with exciton condensation.

From Nature

These tunnelling and electroluminescence characteristics persist up to temperatures of about 100 K. Wang et al. therefore interpret this temperature as the transition temperature for BEC in this system, consistent with previous predictions5.

From Nature

The electron–hole recombination induces strong electroluminescence, the intensity of which has a critical threshold that depends on the exciton density.

From Nature

Electroluminescence and photocurrent generation from atomically sharp WSe2/MoS2 heterojunction p–n diodes.
