Use our efficient implementation to calculate phonon-limited electron mobility (less complex and time-consuming compared to other implementations).Calculate bandstructures and extract effective masses from the bands to be inserted in TCAD advanced transport simulations.

Although it is possible to measure some of these parameters experimentally, it is much simpler and faster to obtain them from atomic-scale simulations with QuantumATK. This, consequently, has a primary impact on the carrier transport in the channel and requires TCAD models to be equipped with new relevant parameters. The change in composition and 2D quantum-mechanical confinement of semiconductor structure in, for example, a nanosheet, significantly alters the bandstructure, resulting in changes to the effective masses and mobility of the carriers relative to bulk materials. With transistor scaling, new channel structures and materials need to be investigated as a means to improve carrier mobility and achieve the target performance.
