Design and fabrication of piezoelectric MEMS SAW pressure sensors

Introduction Micro-Electro-Mechanical Systems (MEMS) pressure sensors have increasingly become critical components in various applications, especially in environments characterized by extreme conditions such as high temperatures, strong radiation, corrosive media, and high pressures. These harsh environments are commonly found in industries such as aerospace, automotive, oil and gas, and nuclear power generation. The unique challenge presented […]

Optimized synthesis of 2D materials using Machine Learning

Introduction Two-dimensional (2D) materials are a class of atomically-thin materials with unique electronic properties that can be exploited to build novel quantum electronics. Initially, carbon was assumed to be the only element with a stable isolatable 2D material phase (graphene) until a new class of compounds called transition metal dichalcogenides (TMDs) were found to also […]

Photoluminescence Spectroscopy of Semiconductors

The goal of this experiment is to use laser light to investigate the band gap energies in semiconductor materials by performing PL spectroscopy.

Magnetic heterostructures and exchange anisotropy

Introduction Ferromagnetism is a form of magnetism where materials exhibit permanent magnetization and strong attraction to external magnetic fields, being the strongest type compared to paramagnetism, diamagnetism, and antiferromagnetism. These materials possess magnetic hysteresis, meaning they retain magnetic alignment even after the external magnetic field is removed, with the level of retained magnetization known as […]

Meaning of Newton’s Laws: How to interpret and understand them (Part 1)

Starters We’ve all probably heard of Newton’s Laws as children and studied them in school. However, many of us would have either misunderstood them or visualised it wrongly. Most of us even forget it after college, except maybe those that take mechanical engineering. While I was not a student of mechanical engineering, I had visualised […]

Welcome to Order in Entropy

Well, first thing’s first. The name of this blog comes from the most common explanation of Entropy, which goes like “Entropy means disorder”, or “Entropy causes disorder”, etc., there are many variants. This blog is to better my understanding of nature and its secrets; and I hope I can be of some help to those […]
