🔍 Key Concepts

• Semiconductor diodes vs. vacuum tubes – which items in the choices are actually semiconductors? • Junction diode construction – what does a "junction" refer to in semiconductor terms? • Point-contact diode construction – how does a point-contact diode make contact with the semiconductor material?

💭 Think About

• Look at each choice and separate the terms that describe semiconductor devices from those that describe non-semiconductor components. • Ask yourself: which two terms are commonly used in basic electronics courses to classify the physical construction of early semiconductor diodes? • Consider which options include words that belong to older tube technology or electrochemical devices, and whether those really describe a semiconductor diode.

✅ Before You Answer

• Verify which terms describe solid-state semiconductor structures (not fluids/electrolytes or vacuum). • Check that both categories in your chosen answer are actually types of diode construction, not power supplies or other components. • Eliminate any option that includes a technology clearly belonging to vacuum tubes or electrolytic cells, since the question is specifically about semiconductor diodes.

Structurally, what are the two main categories of semiconductor diodes?

Junction and point contact.
