Quantum theory and electronic engineering

Click For Summary
SUMMARY

Quantum theory is essential in electronics engineering, particularly in the field of solid-state physics, where it is used to design and model components such as transistors and diodes. Understanding quantum mechanics is crucial for grasping the behavior of materials at the nanoscale, including the development of new materials like graphene. While basic components like resistors and capacitors do not require quantum theory for their design, nanoscale applications necessitate its principles. Advanced courses in thermodynamics and heat transfer further integrate quantum theory through statistical mechanics.

PREREQUISITES
  • Basic understanding of quantum mechanics principles
  • Familiarity with solid-state physics concepts
  • Knowledge of semiconductor materials, particularly silicon

I'm an electronics engineering student and I've only had a introductory one-semester course to quantum mechanics, so I don't really have much knowledge on quantum physics
I'd like to get more information about the topic Quantum Information in electronics

what is real use of quantum theory in electronics engineering field ?
 
Physics news on Phys.org
The field you want is "solid state physics".
Quantum theory is used to build and model very small components.

that means diode transistor are made with silicon atom
so I read quantum theory for components
 
Not just silicone semiconductors ;)
It is now possible to build crystals one layer of atoms at a time - so you get nanometer scale structures with novel properties.
 
all component like resistor , capacitor , inductor transistor made with atom
we can apply quantum theory to design component

Transistors and diodes cannot be understood without quantum theory; you will make use of it when you take a solid state devices course.

Resistors, capacitors, inductors and other linear devices don't require quantum theory to understand or design, though if you make them on the nanoscale the models must take quantum theory into account.

In the future electronics may be based on spintronics; this only makes sense when viewed via quantum theory. New materials such as graphene (single or multiple layers) requires quantum theory; etc. When you take an advanced course in thermodynamics/heat transfer you will find that statistical mechanics depends upon quantum theory.

But in an engineering curriculum they will only teach enough quantum theory so that you can understand what is going on; that is, you will understand it well enough to be able to make use of it in the design of devices or systems. Oftimes this requires only semi-classical quantum theory.
