🔬 Carbon Nanotube Designer
Design CNT structures — chirality (n,m) determines electrical properties
🤔 What Is a Carbon Nanotube?
A carbon nanotube (CNT) is a cylinder of rolled-up graphene — a single sheet of carbon atoms arranged in hexagons. The direction you roll determines everything: the tube's diameter, whether it conducts like metal or acts as a semiconductor, and its incredible mechanical strength (100x stronger than steel at 1/6 the weight).
Why does this matter? By choosing chirality indices (n,m), you control whether a nanotube is metallic or semiconducting. If (n-m) is divisible by 3, it's metallic — enabling ballistic electron transport. Otherwise, it's a semiconductor with a tunable band gap, perfect for nanoscale transistors.
