Transport Models

According to different assumptions in deriving carrier and energy flux equations, macroscopic semiconductor transport models from the moments of the Boltzmann transport equation (BTE) can be divided into two main categories: the hydrodynamic (HD) model which basically follows Bløtekjer's approach [1, 2], and the Energy Transport (ET) model which originates from Strattton's approximation [3, 4]. The formulation, discretization, parametrization and numerical properties of the HD and ET models are carefully examined and compared. The well-known spurious velocity spike of the HD model in simple nin structures can then be understood from its formulation and parametrization of the thermoelectric current components. Recent progress in treating negative differential resistances with the ET model and extending the model to thermoelectric simulation is summarized. Finally, we propose a new model denoted by DUET (Dual ET)which accounts for all thermoelectric effects in most modern devices and demonstrates very good numerical properties. The new advances in applicability and computational efficiency of the ET model, as well as its easy implementation by modifying the conventional drift-diffusion (DD) model, indicate its attractiveness for numerical simulation of advanced semiconductor devices

Insight Into

The objective of this paper is to summarize the recent progress of fin pattern designs. Some of the designs are from the applied patents and some are from the recent literatures. The fin patterns include interrupted surfaces, enhanced wavy and the vortex generators. Benefits and the associated constraints of these designs are discussed. To effectively improve the heat transfer performance, asymmetric designs offer some promising features in the advanced fin patterns. Moreover, concave depression such as cavity design show significant advantages over conventional interrupted fin surfaces. It is recommended that further detailed examinations on the relevant concepts either via numerical simulation or experimental implementation are carried out in the future to gain further insight into the designs.
