0When we talk about electronic devices, then we are dealing with Semiconductors. They have properties lying in between conductors and insulators.
- The resistivities of Silicon and Germanium lies between Conductors and insulators.
- They have a negative temperature coefficient of resistance ( α is proportional to -dR/DT).
- At shallow temperature,ρ of semiconductors matches with insulators.
- Do not follow Ohm's Law, i.e. V-I graph is non-linear.
Space Lattice is defined as an infinite array of points in 3D in which every aspect has an identical environment.
Lattice+ Basis= Crystal structure
