    Semiconductor Fundamentals Price 2.99  |  2.99 Rewards Points

    To understand the fundamental concepts of semiconductors, one must apply modern physics to solid materials. More specifically, we are interested in semiconductor crystals. Crystals are solid materials consisting of atoms, which are placed in a highly ordered structure called a lattice. Such a structure yields a periodic potential throughout the material, which results in some remarkable properties.

    Carrier Transport Price 2.99  |  2.99 Rewards Points

    Any motion of free carriers in a semiconductor leads to a current. This motion can be caused by an electric field due to an externally applied voltage, since the carriers are charged particles. We will refer to this transport mechanism as carrier drift. In addition, carriers also move from regions where the carrier density is high to regions where the carrier density is low. This carrier transport mechanism is due to the thermal energy and the associated random motion of the carriers. We will refer to this transport mechanism as carrier diffusion. The total current in a semiconductor equals the sum of the drift and the diffusion current.

    Metal-Semiconductor Junctions Price 2.99  |  2.99 Rewards Points

    Metal-to-semiconductor contacts are of great importance since they are present in every semiconductor device. They can behave either as a Schottky barrier or as an ohmic contact dependent on the characteristics of the interface. This chapter contains an analysis of the electrostatics of the M-S junction (i.e., the charge, field and potential distribution within the device) followed by a derivation of the current voltage characteristics due to diffusion, thermionic emission and tunneling and a discussion of the non-ideal effects in Metal- Semiconductor junctions.

    MOS Capacitors Price 2.99  |  2.99 Rewards Points

    The primary reason to study the Metal-Oxide-Silicon (MOS) capacitor is to understand the principle of operation as well as the detailed analysis of the Metal-Oxide-Silicon Field Effect Transistor (MOSFET). In this chapter, we introduce the MOS structure and its four different modes of operation, namely accumulation, flatband, depletion and inversion. We then consider the flatband voltage in more detail and present the MOS analysis based on the full depletion approximation. Finally, we analyze and discuss the MOS capacitance.

    MOS Field-Effect- Transistors Price 2.99  |  2.99 Rewards Points

    The n-type Metal-Oxide-Semiconductor Field-Effect-Transistor (nMOSFET) consists of a source and a drain, two highly conducting n-type semiconductor regions, which are isolated from the p-type substrate by reversed-biased p-n diodes. A metal or polycrystalline gate covers the region between source and drain. The gate is separated from the semiconductor by the gate oxide.

    Optoelectronic Devices Price 2.99  |  2.99 Rewards Points

    Optoelectronics deals with the interaction of electronic processes with light and optical processes. Devices in which such interaction can suitably take place, usually accompanied by an energy conversion process (e.g., from electrical to optical, and vice versa), are called optoelectronic devices. Such devices are conveniently made by the semiconductors.

    Heterojunction TED and Power MOSFET Price 2.99  |  2.99 Rewards Points

    A heterojunction is formed when two semiconductors with different bandgaps and lattice constants are brought together, usually by epitaxy. Heterojunctions form essential constituents of almost all electronic and optoelectronic devices.
