We have shown that, in the graded quantum-well wire structures, not only the 'dressed' potential but also the applied direction of the external electric field plays a very important role in the determination of the binding energy.en10.1088/0953-8984/18/27/009info:eu-repo/semantics/closedAccessArticle1827627162632-s2.0-33745509450Q2WOS:000238612900011Q2
