This text explores Kroemer’s Lemma in the context of semiconductor discussions, emphasizing that being able to draw a band diagram is not a definitive sign of understanding the topic. It highlights the importance of clarity in proposals where uncertainties exist and addresses the challenges in designing homework and exams that assess physical understanding without overly relying on mathematics. The potential for exceptional teaching, as exemplified by Herb, is presented, suggesting that there should be recognition for educators who innovate in these areas.

If in discussing a semiconductor problem , you cannot draw a band diagram means you do not know what you are talking Kroemer’s Lemma
If in discussing a semiconductor problem , you can draw a band diagram does not necessarily mean you know what you are talking about An extension of Kroemer’s Lemma
