The goal of the model is to attempt to model the difference between the two semiconductors, that is, the difference with respect to a chosen optimal average (whose contribution to the band offset should vanish). An example would be GaAs-AlAs, constructing it from a virtual crystal of Al 0.5 Ga 0.5 As, then introducing an interface. After this a ...
A logical spreadsheet is a spreadsheet in which formulas take the form of logical constraints rather than function definitions.. In traditional spreadsheet systems, such as Excel, cells are partitioned into "directly specified" cells and "computed" cells and the formulas used to specify the values of computed cells are "functional", i.e. for every combination of values of the directly ...
The 60:40 rule is a heuristic for the specific case of junctions between the semiconductor GaAs and the alloy semiconductor Al x Ga 1−x As. As the x in the Al x Ga 1− x As side is varied from 0 to 1, the ratio Δ E C / Δ E V {\displaystyle \Delta E_{C}/\Delta E_{V}} tends to maintain the value 60/40.
SME book-to-bill ratios (2006–2012, SEMI and SEAJ) The book-to-bill ratio, also known as the BB ratio or BO/BI ratio, [1] is the ratio of orders received to the amount billed for a specific period, usually one month or one quarter.
In semiconductors, the band gap of a semiconductor can be of two basic types, a direct band gap or an indirect band gap.The minimal-energy state in the conduction band and the maximal-energy state in the valence band are each characterized by a certain crystal momentum (k-vector) in the Brillouin zone.
The Shockley diode equation relates the diode current of a p-n junction diode to the diode voltage .This relationship is the diode I-V characteristic: = (), where is the saturation current or scale current of the diode (the magnitude of the current that flows for negative in excess of a few , typically 10 −12 A).
The user may use a variety of languages and tools to create this description. Examples include a C/C++ model, VHDL, SystemC, SystemVerilog Transaction Level Models, Simulink, and MATLAB. RTL design: This step converts the user specification (what the user wants the chip to do) into a register transfer level (RTL) description. The RTL describes ...
Both of these examples are specific to an application (which is typical of an ASIC) but are sold to many different system vendors (which is typical of standard parts). ASICs such as these are sometimes called application-specific standard products (ASSPs). Examples of ASICs are Ethernet network interface controller, flash memory controller, etc.
