Princeton University researchers led by Loren Pfeiffer reported in 2021 GaAs/AlGaAs quantum wells grown by ultra-pure molecular beam epitaxy with a low-temperature electron mobility of about 57 million cm²/(V·s). It is the highest mobility measured in any semiconductor.
The question, scope, and sources behind this Registry record.
Princeton University researchers led by Loren Pfeiffer reported in 2021 GaAs/AlGaAs quantum wells grown by ultra-pure molecular beam epitaxy with a low-temperature electron mobility of about 57 million cm²/(V·s). It is the highest mobility measured in any semiconductor.
The highest electron mobility ever measured in any semiconductor structure.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
