In the lecture of “System LSI”, told us the professor.
“Years ago, there was an incident, that had changed my idea of teaching dramatically.”
“In the examination I made a question – which is the right carrier of nMOS, an electron or a positve hole?”
“I had expected that to this question, 70% of the students could write as electron(電子), 20% would write as positive hole (正孔), and the rest 10% could not write anything.”
“But looking at the answer sheets I was shocked –
Only 30% wrote as 電子, 30% worte as 正孔, and 20% wrote as 孔子.”
孔子 is the name of a famous philosopher in ancient China. In English he might be called “Confucius.”
“孔子 might have brought various ideas, but no electric charge, I suppose. I beg you, my students, please don’t be confused and select one from the two options. Please do not synthesize your own answer. “
