Unfortunately, this approach does not involve truly free electrons and holes – but rather excitons, which are bound pairs of electrons and holes. Although excitons can be separated into free charges ...

Free electrons can be used to generate light by passing them through a periodic structure. ... G. Free electrons get light out of a hole. Nature Nanotech 4, 707–708 (2009) . https://doi ...

In addition, the concentrations of free electrons and/or holes can be controlled independently of Mn content by the addition of impurities, ...

"Excitons" arise from stable association between electrons and holes. The researchers used their new collider to test the binding energy of excitons -- how much energy it takes to pull an exciton ...
