    Convention
In summary, the conversation discusses the terminology used for n-p type semi-conductors and the reason behind it. It is explained that this terminology is based on the excess of holes in p-type material and excess of electrons in n-type material. Additionally, it is mentioned that the formation of a junction results in the P-type side becoming negative and the N-type side becoming positive.

Homework Statement


I am reading a chapter on semi-conductors in a text.It talks about n-p type semi-conductors and states that "the potential of the n-side is higher than that of the p-side"

However, by convention, in case of batteries for example,we designate the negative terminal as lower potential and the positive terminal as higher potential.

So, what can be the reason behind the author's terminology?

Thanks.

P-type material has an excess of holes. N-type material has an excess of electrons. This is the reason they are called P and N type.

It just happens that when a junction is formed the holes and electrons diffuse across the junction making the P-type side negative and the N-type side positive.
 

1. What is departure from convention?

Departure from convention refers to straying away from traditional or standard practices or norms. It involves breaking away from the expected or usual way of doing things.

2. Why is departure from convention important in science?

Departure from convention is important in science because it allows for new and innovative ideas to be explored and tested. It encourages critical thinking and challenges existing beliefs, leading to advancements and breakthroughs in the scientific field.

3. What are some examples of departure from convention in science?

Some examples of departure from convention in science include the discovery of the structure of DNA by James Watson and Francis Crick, the theory of relativity by Albert Einstein, and the invention of the internet by Tim Berners-Lee. These ideas and inventions challenged traditional beliefs and revolutionized the way we understand and interact with the world.

4. What are the potential risks of departure from convention in science?

The potential risks of departure from convention in science include the possibility of failure or rejection from the scientific community. It may also lead to controversy and criticism, especially if the new ideas go against established theories and beliefs. However, these risks are necessary for progress and can ultimately lead to significant advancements.

5. How can scientists ensure responsible departure from convention?

Scientists can ensure responsible departure from convention by conducting thorough research and experiments to support their ideas, seeking peer review and feedback, and being open to criticism and further testing. It is also important to consider the ethical implications of new ideas and to communicate them clearly to the public.
