Figure 12-5. Representation of the calculated injection current on a In 7 vs 7 scale. The dashed hne indicates the slopes predicted by Fowler Nordheim tunneling theory for A=0.8eV assuming that the effective mass equals the free electron mass. Figure 12-5.

It is obvious that the device efficiency, rj, must also be very sensitive to the barrier height, since the efficiency is limited by upon the minority carrier density. As suggested by Eqs. (4.3) and (4.4), Fig. 4.13 plots rt(r]) vs >3/2. The excellent agreement between the theory and the data confirms the use of the Fowler-Nordheim tunneling model for describing the carrier injection into the band structure of the semiconducting polymer. [Pg.164]

Field emission, also known as Fowler-Nordheim tunneling, is the process by which electrons tunnel through the work function barrier at a surface in the presence of a high electric field and are emitted into the vacuum. Fowler-Nordheim theory is generally used to quantitatively describe the... [Pg.293]

The escape of electrons from traps by tunneling bears the same relation to the Poole-Frenkel theory as does the Fowler-Nordheim theory to the Schottky theory. It gives a law similar to the Fowler-Nordheim law. [Pg.224]

Eield emission (EE) (also known as field electron emission or electron field emission) is the emission of electrons from a solid surface into vacuum induced by an electrostatic field. FE was first explained by quantum tunneling of electrons in the late 1920s [1], and the theory of FE from bulk metals was proposed by Fowler and Nordheim [2]. A family of approximate equations, called Fowler-Nordheim equations (F-N equations), are named in their honor and have been shown in terms of experimentally measured quantities as... [Pg.233]
