A fair split would look like 2.5% to the buyerâs agent and 2.5% to the sellerâs agent. But with discount brokers, the split is not always as fair as it should be. With a discount broker, the seller is told that he or she will have to pay a lower fee or commission because the discount broker is offering a great deal.
Thermionic emission Thermionic emission is the heat-induced flow of charge carriers from a surface or over a potential-energy barrier. This occurs because the thermal energy given to the carrier overcomes the binding potential, also known as work function of the metal.
Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. This type is called a thermionic tube or thermionic valve. A phototube, however, achieves electron emission through the photoelectric effect.
