Chapter 4: Advanced Synthesis Techniques

ALD, Electrodeposition, Additive Manufacturing

4.1 Atomic Layer Deposition (ALD)

ALD enables atomic-level control through sequential self-limiting surface reactions.

πŸ“ Film Thickness: $$t = N_{cycles} \times GPC$$ where GPC is growth per cycle

# Requirements:
# - Python 3.9+
# - matplotlib>=3.7.0
# - numpy>=1.24.0, <2.0.0
