North Carolina State University Researchers found that coating gallium
nitride (GaN) with a layer of phosphorous-derived acid can make LEDs that are
both brighter and more resilient than traditional white LEDs.
“By coating polar GaN with a self-assembling layer of phosphonic
groups, we were able to increase the luminescence without increasing energy
input, ” says …
