ABSTRACT
This chapter presents an overview of two nanoscale systems, namely, molecular magnets and semiconductor quantum dots. It looks into the theory and modeling of these two nanoscale systems, and addresses some of the critical research issues in the fast-evolving field of nanomagnetism and nanoelectronics where molecular magnets and quantum dots are the respective building blocks. Molecular magnets and semiconductor quantum dots are well defined by experiment and are tractable using standard theoretical and computational tools. To this effect any complete theoretical and modeling initiative aiming to understand such systems should focus on creating a unique theoretical and modeling expertise, exploring novel theories and models to predict behavior and reliability of functional nano-size sensors and devices, and understanding classical transport mechanisms at nanoscales. Modeling with MATLAB attempts to give a brief and basic understanding of a key and versatile tool that can be used effectively in many computational settings.
