ISBN Copper has 20 orbiting electrons with only one electron in the outermost shell. The fact that the outermost shell with its 29th electron is incomplete subshell can contain 2 electrons and distant from the nucleus reveals that this electron is loosely bound to its parent atom. The application of an external electric field of the correct polarity can easily draw this loosely bound electron from its atomic structure for conduction. Both intrinsic silicon and germanium have complete outer shells due to the sharing covalent bonding of electrons between atoms.

Electrons that are part of a complete shell structure require increased levels of applied attractive forces to be removed from their parent atom.

Intrinsic material: an intrinsic semiconductor is one that has been refined to be as pure as physically possible. That is, one with the fewest possible number of impurities. Negative temperature coefficient: materials with negative temperature coefficients have decreasing resistance levels as the temperature increases. Covalent bonding: covalent bonding is the sharing of electrons between neighboring atoms to form complete outermost shells and a more stable lattice structure.

An n-type semiconductor material has an excess of electrons for conduction established by doping an intrinsic material with donor atoms having more valence electrons than needed to establish the covalent bonding. The majority carrier is the electron while the minority carrier is the hole. A p-type semiconductor material is formed by doping an intrinsic material with acceptor atoms having an insufficient number of electrons in the valence shell to complete the covalent bonding thereby creating a hole in the covalent structure.

The majority carrier is the hole while the minority carrier is the electron. A donor atom has five electrons in its outermost valence shell while an acceptor atom has only 3 electrons in the valence shell.

Majority carriers are those carriers of a material that far exceed the number of any other carriers in the material. Minority carriers are those carriers of a material that are less in number than any other carrier of the material.

Same basic appearance as Fig. For forward bias, the positive potential is applied to the p-type material and the negative potential to the n-type material. For most applications the silicon diode is the device of choice due to its higher temperature capability. Ge typically has a working limit of about 85 degrees centigrade while Si can be used at temperatures approaching degrees centigrade.

Silicon diodes also have a higher current handling capability. Germanium diodes are the better device for some RF small signal applications, where the smaller threshold voltage may prove advantageous.

From 1. VF decreased with increase in temperature 1. Usually, however, technology only permits a close replica of the desired characteristics. The most important difference between the characteristics of a diode and a simple switch is that the switch, being mechanical, is capable of conducting current in either direction while the diode only allows charge to flow through the element in one direction specifically the direction defined by the arrow of the symbol using conventional current flow.

As the reverse voltage increases, the reverse resistance increases directly since the diode leakage current remains constant.

Germanium: 0. GaAa: 1. The transition capacitance is due to the depletion region acting like a dielectric in the reverse- bias region, while the diffusion capacitance is determined by the rate of charge injection into the region just outside the depletion boundaries of a forward-biased device. Both capacitances are present in both the reverse- and forward-bias directions, but the transition capacitance is the dominant effect for reverse-biased diodes and the diffusion capacitance is the dominant effect for forward-biased conditions.

As the magnitude of the reverse-bias potential increases, the capacitance drops rapidly from a level of about 5 pF with no bias. For reverse-bias potentials in excess of 10 V the capacitance levels off at about 1.

The results support the fact that the dynamic or ac resistance decreases rapidly with increasing current levels. Using the bottom right graph of Fig. For germanium it is a 6. Levels of part c are reasonably close but as expected due to level of applied voltage E.

The threshold voltage of 0. Since all the system terminals are at 10 V the required difference of 0. Vdc 2V VLm Positive half-cycle of vi: Voltage-divider rule: 2. Polarity of vo across the 2. Voltage-divider rule: 2. However, vo is connected directly through the 2. For the positive region of vi: The right Si diode is reverse-biased. For the negative region of vi: The left Si diode is reverse-biased.

Network of Fig. VL VZ The maximum level of I Rs will in turn determine the maximum permissible level of Vi. Any value of vi that exceeds For a 5 V square wave neither Zener diode will reach its Zener potential.
