Meshing – New Features in 2019 Baseline Release

The 2019 TCAD baseline release of Victory Mesh now contains Solid Modeling functionality. The term Solid Modeling is used to refer to a methodology that generates or manipulates a device via geometrical operations, for example, bending, mirroring and joining or insertion.

Device Simulation – New Features in 2019 Baseline Release

The effect of Coulomb interaction in the absorption spectrum of quantum wells (QWs) is responsible for the quantum confined Stark effect (QCSE), which is the physical mechanism underlying the operation of electro-absorption modulators [1]. A new model has been added to Atlas to simulate QCSE in QWs and can be enabled with the following command (the qwell model must also be activated):

Interactive Tools – New Features in 2019 Baseline Release

DeckBuild is Silvaco’s state of the art simulator interface. It is capable of running all simulators from Silvaco as well as many of the visualization tools. Figure 4-1 shows an overview where a simulation was successfully finished and the results can be inspected. Values that were extracted from a structure file are shown in the top right part of the window.

3D TFT Simulation of Grains and Grain Boundaries

IntroductionLow-temperature polycrystalline silicon (LTPS) thin-film transistors have been widely applied to AMOLED (Active Matrix Organic Light Emitting Diode) as the most suit­able means for high mobility, high switching speed and high resolution [1-2].A Laser Annealing Process such as Excimer Laser Annealing (ELA) is used to manufacture by converting Amorphous Silicon (a-Si) to Polycrystalline Silicon (poly-Si) at low temperature. The poly-Si structure (produced through ELA) shows the laser wavelength, pulse width and spatial beam dependencies.

Quantum Dot-Based Hybrid Light Emitting Diode Modelling Using Radiant

IntroductionWith the recently launched Radiant, a graphical user interface (GUI) for Atlas-based TCAD simulations, the entry barrier for inexperienced users has been lowered. In particular, the use of guided simulation tools, for both experienced and novice researchers, can speed up the development cycle. Light emitting diodes (LEDs) have caught the attention of the scientific community for many years, especially organic-based light emitting diodes (OLEDs) and the emerging quantum dot-based light emitting diodes (QD-LEDs).

Verification of an Compact Model for Organic Thin-Film-Transistors by Using MixedMode Creating an CMOS Inverter Circuit with TCAD Transistor Devices

Organic thin-film transistors (OTFTs) are promising devices for future low-cost electronics[1][2]. However, to enable the development of this technology, circuit design simulation is needed. TCAD with MixedMode approach provides a suitable route for the physics based simulation of these transistors within simple circuits. As circuits become more complicated, more devices are needed and the computing time increases significantly. Compact models describe the behavior of the device with only a few equations and thus the computing time is reduced to a viable magnitude. Such equations are written down in a Verilog-A format which can be used by most SPICE simulators.
