Fabrication and characterization of quantum Hall devices for the resistance standard at CMS

Abstract: We fabricated AlGaAs/GaAs heterostructurebased quantum Hall devices for the resistance standard at Center for Measurement Standards (CMS). The measurements using a Direct Current Comparator (DCC) show the consistency between the plateaus of =2 and 4 at the temperature T=2 K, where is the filling factor. On the other hand, the plateaus of higher filling factors may be susceptible to the reduced localization strength, under which the semiclassical effects can be important. The

“…These structures give the wings their water-repellent properties and prevent bacterial adhesion. The intricate patterns on cicada wings create a surface that is not only water-resistant but also impedes the agglomeration of organic matter and nutrients for bacteria growth [67,[69][70][71]. Bacteria can be eliminated easily from these cicada wings due to the combination of micro and nano protrusions that provide waterrepelling characteristics, which affects their growth and colonization [46,69,72].…”
