Z-Scan: A Tool to Explore Third Order Nonlinearity

This short note breifly discuss about the optical nonlinearity and way to characterize it. To an extend methodology, experimental setup and physics behind the z-scan results are discussed.

DFT - FAQs

This handout I prepared to send to a friend, who wish to start his endevour in DFT. (Later, he changed his decision!). Whoever wonder what is DFT, this very short note may (or may not) help.

M. Sc. Materials Science Record

This is the bare minimum record for materials science laboratory. (Note: This was prepared when I handled M.Sc. Materials Science Lab in Bharathidasan University).

Writing with LaTex and Git

This documentation aims to provide a brief yet complete account of integrating LaTex with Git. In addition, when the project is integrated with github, it provides seamless collaboration and cloud-syncing.

Substrate Cleaning

In order to slightly etch the surface or to completly remove any organic residuals piranha solution can be used. This short handout describes how to prepare and use the piranha solution for sillicon wafer cleaning.

Choice of basis and functional

ORCA ESD module offers possibility to easily model optoelectronic properties of molecular systems. However, the calculations are computationally expensive. Analysed here simple and satisfactory DFT method for such calculations using benzene.
