### 2.1 General Chemistry and Structure

| We had the following class exercises:
|  | Ponder the history of "LCD" flat panel displays.
|  | Why does the world need saving? How shall it be done?
|  | Why do we use crystals, preferably single crystals, preferably "perfect" single crystals in case of doubt?
|  | Supply examples for critical parameter - component couplings.
|  | What makes a semiconductor interesting for technology?
|  | How would you like your bandgap, Sir?
|  | What does it mean to dope a semiconductor in reality?
|  | Come up with 2 - 3 examples where product requirements transfer to shape / structure requirements.
|  | Can you still afford it if your present product is hugely successful? - What could that mean?
|  | Provide examples (and criteria) for the products listed
