Solid State Physics vs Electronics Engineering

Click For Summary

Discussion Overview

The discussion centers on the differences between solid state physics and electronics engineering, particularly from the perspectives of both fields regarding circuit design and device development. Participants explore the scope of solid state physics, its applications, and the training differences between physicists and engineers.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant seeks clarification on the differences between solid state physics and electronics engineering, emphasizing the practical aspects of circuit design and analysis.
  • Another participant notes that solid state physics encompasses a broader range of topics beyond semiconductors, including magnetism and superconductivity, and highlights the goal of discovering new devices rather than just combining existing ones.
  • It is mentioned that while most physicists may not be as well trained in circuit design as electronics engineers, there are exceptions, particularly in specialized projects like CERN detectors.
  • A participant asserts that much of the circuit design for CERN detectors was primarily conducted by electrical engineers, with physicists contributing mainly to system design and integration rather than core electronics development.
  • One participant acknowledges a correction regarding the contributions of physicists and engineers in the context of CERN detector design.

Areas of Agreement / Disagreement

Participants express differing views on the roles and training of physicists versus engineers in circuit design, with some agreeing on the general trend but noting exceptions. The discussion remains unresolved regarding the extent of contributions from each field in specific projects.

Contextual Notes

There are limitations in the discussion regarding the specific training and expertise of physicists and engineers, as well as the varying contexts in which they operate, which may influence their capabilities in circuit design.

Forgive me for asking this question if the answer is obvious. The truth is I have a BENG in electrical engineering and want to know the differences between the two.
From an engineer's perspective its about knowing what you can do with the devices in a useful way and design, analyze and build the circuit.
I'd like to know the Physicist's perspective and I'm also keen to know whether a Physicist is just as well trained as an engineer in designing circuits.
Thanks

Solid state physics covers many more subjects than just semiconductor devices: Magnetism, Superconductivity, Metals, and so on are just simple examples, there are many more.

For semiconductor physics, the goal is not usually to combine existing devices to make circuits, but to find new ways to make devices.

The transistor was invented by (solid state) physicists. So was the laser.

Most physicists will not be trained as well in circuit designs as electronics engineers. But there are exceptions. There are physicists working on the electronics of the CERN detectors, for example, that are developing circuits that are state of the art in every sense. On the other hand I also know physicists that cannot tell a diode from a resistor or capacitor.

I agree with the beginning of your quote but most of the circuit design for the detectors at CERN (I have specific knowledge primarily of the ATLAS detector) was done by Electrical Engineers. There are some very knowledgeable physicists on the project to be sure, but their contributions are mostly on the system design, evaluation, system integration, and software development and less on the hard-core electronics development (not least the IC development which was done almost entirely by EEs and a couple of physicists turned EEs).
 
That is quite possible. I stand corrected.
