Heterojunctions are formed by combining two dissimilar semiconducting materials, such as aluminum-arsenic or gallium-phosphorus, which results in unequal band gaps compared to homojunctions. The document defines heterojunction band diagrams and discusses the electric field and electric potential that arise at the junction between dissimilar materials.

- 2. What are heterojunctions? • Heterojunctions are formed by combining of two dissimilar metals e.g. aluminum-arsenic, gallium-phosphorus, gallium-arsenic • Heterojunctions have unequal band gaps as opposed to Homojunctions
- 4. Defining electric field and electric potential
