Hirmer, Michael and Schuh, Dieter and Wegscheider, Werner (2011) Carbon doped InAlAs/InGaAs/InAs heterostructures: Tuning from n- to p-doping. Applied Physics Letters 98, 082103.
We fabricated carbon doped InAs/ InxGa1−xAs/ InxAl1−xAs heterostructures, which show p-type and n-type conductivity for different In contents. Two-dimensional hole gas in a structure with x =0.75 has been prepared in the ternary compound, despite the fact that carbon as an n-type dopant in InAs exhibits electron conductivity in InxGa1−xAs and InxAl1−xAs compounds with high indium content. A ...
