SUMMARY

The discussion clarifies that there are no semiconductors classified strictly as "heavy metals." Instead, some semiconductor materials may contain heavy metals as part of their compounds or through doping processes. Toxicity cannot be determined solely by the presence of heavy metals; it varies based on the specific compound. For accurate toxicity information, users are advised to consult the Material Safety Data Sheets (MSDS) of the relevant semiconductor materials.

PREREQUISITES
  • Understanding of semiconductor materials and their classifications
  • Familiarity with doping processes in semiconductor technology
  • Knowledge of Material Safety Data Sheets (MSDS) and their importance
  • Basic chemistry concepts regarding compounds and toxicity
NEXT STEPS
  • Research semiconductor doping techniques and their implications
  • Study the toxicity profiles of specific semiconductor compounds
  • Learn how to interpret Material Safety Data Sheets (MSDS)
  • Explore the relationship between heavy metals and their compounds in electronics
USEFUL FOR

Engineers, chemists, and safety professionals involved in semiconductor manufacturing and materials science, as well as anyone concerned with the toxicity of electronic components.

Is there a list of semiconductors that are heavy metals?

Here is an extensive list of semiconductor materials.
Some of them are compounds of elements involving heavy metals.

The reason I was asking for a list of heavy metal semiconductors was because I wanted to know which ones would be toxic. I checked the wikipedia page but was unable to find which ones were toxic.

This is puzzling. Just because an element by itself is toxic doesn't mean that in a compound, it is still toxic. You do not want to ingest sodium and inhale chlorine separately, but in NaCl, it can be consumed.

There are no "heavy metal" semiconductors, because by definition they are not! There are, however, semiconductors that have been doped with them, or that they are part of a compound that form the semiconductor. The toxicity of the semiconductor cannot be determined simply by the presence of a heavy metal element, but this is true with most material, so one has to assume that you do not want to swallow any of them.

Look up the MSDS of a particular compound or material that you are curious about. If it is toxic, it will state it there.
