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.
The metal then emits a current of electrons. This is called thermionic emission. It is important for applications such as electron tubes and fluorescent lamps. The amount of thermionic emission depends not just on temperature, but also on how much energy electrons inside the metal need to escape. Now the energies of the most energetic electrons inside the metal are best expressed in terms of the Fermi energy level.
