🔬 Nanotechnology Fundamentals

Nanotechnology involves engineering at the nanoscale, where quantum effects become significant.

Quantum Confinement

The energy levels of quantum dots:

E = (h²π²n²)/(2mL²)

Where E is energy, h is Planck's constant, n is quantum number, m is mass, and L is size.

Surface-to-Volume Ratio

The ratio of surface area to volume for nanoparticles:

S/V = 3/r

Where S is surface area, V is volume, and r is radius.

Self-Assembly Energy

The energy of self-assembly processes:

E_assembly = -k_BT × ln(Ω)

Where k_B is Boltzmann constant, T is temperature, and Ω is configuration number.
