The Impact

With the development of IC manufacturing process, the device dimensions have been on the nanoscale, while the device performance, such as the electron velocity, mobility and thermal noise, is significantly affected by the hot carrier effect. This paper proposes an electron temperature model to accurately predict the hot carrier effect. The channel transverse electric field is firstly derived by using the channel electric potential equation, taking into account the boundary conditions of the electric field. Based on the electric field equation, the energy balance equation is solved involving the impact of the temperature gradient and then the electron temperature model is established. The impact of the electron temperature on the channel mobility and of temperature gradient on the electron velocity has also been investigated. The results show that when the device enters the nanoscale, the electron mobility is more susceptible to the influence of the electric field and the electron temperature, and the impact of the temperature gradient on the velocity becomes obviously greater. The electron temperature model proposed in this paper can be applied to the performance analysis and modeling of nanosized MOSFETs.

The internal average energy loss caused by entropy generation for steady mixed convective Poiseuille flow of a nanofluid, suspended with titanium dioxide (TiO2) particles in water, and passed through a wavy channel, was investigated. The models of thermal conductivity and viscosity of titanium dioxide of 21 nm size particles with a volume concentration of temperature ranging from 15 °C to 35 °C were utilized. The characteristics of the working fluid were dependent on electro-magnetohydrodynamics (EMHD) and thermal radiation. The governing equations were first modified by taking long wavelength approximations, which were then solved by a homotopy technique, whereas for numerical computation, the software package BVPh 2.0 was utilized. The results for the leading parameters, such as the electric field, the volume fraction of nanoparticles and radiation parameters for three different temperatures scenarios were examined graphically. The minimum energy loss at the center of the wavy channel due to the increase in the electric field parameter was noted. However, a rise in entropy was observed due to the change in the pressure gradient from low to high.
