Weak antilocalization effect in high-mobility two-dimensional electron gas in an inversion layer on p-type HgCdTe
Weak antilocalization effect in high-mobility two-dimensional electron gas in an inversion layer on p-type HgCdTe
Magnetoconductance of a gated two-dimensional electron gas (2DEG) in the inversion layer on p-type HgCdTe crystal is investigated. At strong magnetic fields, characteristic features such as quantum Hall effect of a 2DEG with single subband occupation are observed. At weak magnetic fields, weak antilocalization effect in ballistic regime is observed. …
