What role does physics play in materials science?

AI Thread Summary
Physics plays a crucial role in materials science, particularly through solid state physics, which serves as its theoretical foundation. Essential knowledge includes quantum mechanics, thermodynamics, and statistical mechanics, especially for understanding phase transitions and high-temperature behaviors. Techniques like density functional theory are vital for computational studies of crystalline solids. Electromagnetics is important for those focusing on ferroelectric and magnetic materials, while electrochemistry and liquid state physics are relevant for studying interfaces. A comprehensive understanding of these physics concepts is necessary for effective work in materials science.

Hello.
I would like to hear of somebody with experience in the area of materials science (theoretical/computational or experimental) the answer to the following question: What kind of Physics knowledge one must have to work in this area. I mean, how much of the basic Physics stuff you must know and how do you use it in your work. I have been asking myself this because to me it looks like none of the advanced stuff (like quantum mechanics, advanced electromagnetism, statistical physics, solid state, etc) is really used in the area and what trully matters is knowing the things only related to materials characteristics, things that I think are more common that a chemist would know. Since I don't know anyone who works in the field, I asked here.
Thanks in advance.

I would suggest you open a solid state textbook, such as the one by Kittel or Ashcroft/Mermin. After you get through the free-electron/Drude model, practically everything else is the application of quantum mechanics! Just look at the Bloch wavefunction for starters.

Solid state physics is the theoretical basis for materials science. For computational materials science you might want to look into techniques like density functional theory.
 
Thermodynamics and statistical mechanics are needed whenever you study materials that undergo phase transitions, or high temperatures/pressures are important
Elasticity theory and continuum mechanics are needed when studying the impact of defects on the mechanical properties.

Electromagnetics is necessary for those work in ferroelectric and magentic materials.

As mentioned above solid state physics/ Density functional theory are needed whenever you study crystalline solids.

If you plan to study water/semiconductor or water/metal interfaces then a bit of electrochemistry and liquid state physics are needed.

If you study amorphous metal oxides then you may need all the above :biggrin:
 
After a year of thought, I decided to adjust my ratio for applying the US/EU(+UK) schools. I mostly focused on the US schools before, but things are getting complex and I found out that Europe is also a good place to study. I found some institutes that have professors with similar interests. But gaining the information is much harder than US schools (like you have to contact professors in advance etc). For your information, I have B.S. in engineering (low GPA: 3.2/4.0) in Asia - one SCI...
Bit Britain-specific but I was wondering, what's the best path to take for A-Levels out of the following (I know Y10 seems a bit early to be thinking about A-levels, but my choice will impact what I do this year/ in y11) I (almost) definitely want to do physics at University - so keep that in mind... The subjects that I'm almost definitely going to take are Maths, Further Maths and Physics, and I'm taking a fast track programme which means that I'll be taking AS computer science at the end...
I graduated with a BSc in Physics in 2020. Since there were limited opportunities in my country (mostly teaching), I decided to improve my programming skills and began working in IT, first as a software engineer and later as a quality assurance engineer, where I’ve now spent about 3 years. While this career path has provided financial stability, I’ve realized that my excitement and passion aren’t really there, unlike what I felt when studying or doing research in physics. Working in IT...
