  • Classical and quantum semiconductor device modeling and simulation
    prof. Ansgar Jungel, Universitaet Mainz, Germany
    giovedì 10 ottobre 2002 alle ore 14:30, Aula Seminari MOX – Dip. mat.
    ABSTRACT
    The numerical simulation of modern semiconductor devices, like deep
    submicron transistors or tunneling diodes, using microscopic models is
    usually costly and time consuming. In recent years, fluiddynamical models
    are derived, which contain the main physical phenomena and which can be
    solved efficiently.

    In this talk, a model hierarchy of classical and quantum fluid equations
    for semiconductor devices is introduced and two models of this hierarchy
    are discussed in detail: the quantum drift-diffusion equations and
    the energy-transport models. A positivity-preserving numerical scheme
    for the quantum drift-diffusion model is derived and numerical convergence
    is proved. A simple 1D resonant tunneling diode is simulated showing
    the expected physical behavior. Moreover, the classical energy-transport
    equations are discretized using adaptively refined mixed finite elements
    and a 2D MOSFET is numerically simulated.
  • Quantum-mechanical simulation of nanoscale MOSFET s
    dr. Agostino Pirovano, Dipartimento di Elettronica, Politecnico
    giovedì 10 ottobre 2002 alle ore 15:30, Aula consiglio – 7° piano dip. mat.
    ABSTRACT
    Quantum-mechanical (QM) simulation of aggressively
    scaled MOSFET s has become a compelling issue for
    sub-0.1 um channel lengths, where semiclassical approaches
    are expected to become highly unreliable. In these
    conditions, even 1D and quasi-2D QM models become
    questionable and a fully 2D treatment of QM effects
    is required. In this talk I will discuss the role played
    by QM effects in deep sub-micron MOSFET s simulations,
    presenting results obtained with a highly-effective fully
    2D self-consistent QM model. The numerical details and the
    computational issues of the 2D-QM model will be addressed and
    discussed. Comparing classical and quantum results, the
    quantitative impact of QM effects in very short channel
    devices will be investigated, forecasting the sub-50 nm
    MOSFET s performances.
