4.1 Atomic Layer Deposition (ALD)
ALD enables atomic-level control through sequential self-limiting surface reactions.
📐 Film Thickness: $$t = N_{cycles} \times GPC$$ where GPC is growth per cycle
💻 Code Example 1: ALD Growth
# Requirements:
# - Python 3.9+
# - matplotlib>=3.7.0
# - numpy>=1.24.0, <2.0.0
