Morphology
The listed common meaning of 'dope' (to give drugs) combined with 'up' (to increase) does not transparently yield the technical sense of introducing impurities into semiconductors; the MWE relies on a specialized materials‑science sense of 'dope' that B1 learners are unlikely to know. Because the required meaning is domain‑specific and distinct from everyday senses of the constituents, learners who only know the common meanings would not predict this usage.
Etymology
Dope up In electronics and engineering, dope up comes from the idea of adding a little dope (an extra chemical) to change how a material behaves. Think of adding a small ingredient to a recipe to change the taste—engineers add tiny amounts of another element to silicon, so the phrase means 'to add a small amount of something to change a material's properties'.
