Fundamental diode model

In previous sections we have commented on the success of the fundamental diode model, based on electron density in the conduction band, and phenomenological... 

The commercial application of polymer blend technology has grown significantly such that, today, compositions are available with properties that once were substantially unattainable with homopolymers. To date, polymer blends have been applied in optical fibers [13,14], microlenses [15], liquid crystal display components [16,17], solar cells [18-20], nonionizing radiation detection [21] and polymer light-emitting diodes [22-24]. In particular, the use of developed polymer blends in optoelectronics applications appears unlimited. Polymer blends may also provide model systems in statistical physics when studying the fundamental aspects of equilibrium and nonequilibrium properties [3], optical properties [25], and mechanical and electrical properties [26]. 

In Electrical Engineering, the semiconductor diode provides one of the most fundamental nonlinear devices. The current in die forward or conduction region is approximately an exponential function of diode voltage. Data for such a semiconductor diode is shown in Figure 9.48, along with a typical model equation of the form ...
