Abstract
The authors report the results of a systematic study of light-emitting devices made of porous silicon. The threshold for detectable electroluminescence is 5 V, the external efficiency reaches 0.01% at larger voltages and the LED output is stable for more than 100 hours of operation.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
