Quantum Workshop IV: Modeling PN Junctions
16 Mar 2015 | Teaching Materials | Contributor(s): Stella Quinones
Students explore the PN Junction Simulation Tool in order to understand depletion, carrier modeling, and PN junction device physics. Analyze (i) carrier concentration and electric field as a function of doping, and (ii) energy barriers, depletion widths, and net charge density as a function of...
Quantum Workshop III: LED Circuit and Device Physics
07 Feb 2015 | Teaching Materials | Contributor(s): Stella Quinones
A hands-on learning exercise used to illustrate the device physics of a light emitting diode (LED) in a simple resistor circuit. Students explore the photon energy of four LEDs, compare the voltage drop (or forward bias) across the LED, and explain the behavior of the LED under...
Quantum Workshop II: Energy Band Model and Doping
31 Jan 2015 | Teaching Materials | Contributor(s): Stella Quinones
This exercise uses several nanoHUB tools associated with fundamental semiconductor device knowledge, such as the Effect of Doping on Semiconductors, Semiconductor Doping, and Carrier Concentration tools. Students are asked to compare bond models with energy band models, examine...
Quantum Workshop I: Two Slit Experiment
Exercise using the "Particle-Wave Duality: an Animation" on nanoHUB as an introduction to an undergraduate quantum mechanics course. A series of questions allow students to analyze what is happening in the 2-slit experiment and to make conclusions about the behavior...
Intro to MOS-Capacitor Tool
09 Jan 2013 | Tools | Contributor(s): Emmanuel Jose Ochoa, Stella Quinones
Understanding the effect of silicon doping, oxide (SiO2) thickness, gate type (n+poly/p+poly), and semiconductor type (n-type/p-type) on the flatband voltage, threshold voltage, surface potential and oxide voltage of a MOS-Capacitor.
