In this work, we were able to evaluate the tunability of Rashba-SOI-related parameters in the 2DHG system of In0.75Al0.25As/In0.75Ga0.25As/InAs: Mn quantum well heterostructures experimentally by analyzing the hole density evolution of quantum interference effects at low magnetic fields. We achieved to cover a significant range of hole densities by the joint action of the variation of the manganese modulation doping concentration during molecular beam epitaxy and external field-effect-mediated manipulation of the 2D carrier density in Hall bar devices by a metallic topgate.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/3/86/845/137/3868451374_b.jpg", "price_data" : { "retail_price" : "39.00", "online_price" : "39.00", "our_price" : "39.00", "club_price" : "39.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
