In this paper, a comprehensive comparison of TFET simulations using two TCAD simulators, Sentaurus and Silvaco TCAD, is presented. The comparison is fully cover various types of TFETs, either from the structure geometry or the materials point of view, which proved a framework for TFET designs and simulations. For Sentaurus TCAD, a dynamic nonlocal BTBT model is used for all simulations as it is proved a good calibration for experimental data or full quantum data taken from the literature. The BTBT model’s parameters are determined for different material and hetero-junctions structures where they can be used directly for any design or structure calibration. For the Silvaco simulator, a nonlocal BTBT model is utilized for calibration and its parameters are also provided. The study offers quick parameters data to be used directly, utilizing various materials without being involved in calibration difficulties.

Image fusion is a basic tool for combining low spatial resolution multi-spectral image and high spatial resolution panchromatic image using advanced image processing techniques. Many approaches have been developed to combine these images to obtain a fused one. Intensity-hue-saturation IHS transform is one of the widespread image fusion methods in the remote sensing community. However, this method introduces color distortion; therefore many papers have investigated modifications for the IHS method that can reduce this problem.In this paper, a filterbank-enhanced IHS method is developed for fusing satellite images. In this method a group of filters (a low pass filter, a high pass filter and several band pass filters) are used for filtering the panchromatic image and the intensity component of the original multispectral image. The resultant filtered images are combined to obtain a fused image. Experimental results indicate that filterbank-enhanced IHS method gives improved results relative to other fusion techniques.
