Dacal Erasmo A. de Andrada e Silva Física, Astronomía y Matemáticas Conductance Influence of dimensionality Effective mass approximation The influence of dimensionality on the conductance of semiconductor cross junctions is investigated in theeffective mass approximation and quantum ballistic regime. Our calculations exhibit some similar features forboth two- and three-dimensional models, namely the conductance peaks before the fundamental eigenenergyof the quantum wire that represents the sidearms and the zero conductance dip. Despite this, we show that, ingeneral, the conductance and the electronic wave function are strongly affected when the third spatial dimensionis taken into account. In other words, we prove that two-dimensional models are not suitable for representingthis kind of system. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436336 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2A Vol.36 |
