Exciton binding energy in a quantum-well wire

Transverse Stark effect of electrons in a semiconducting quantum wire

“…Following an approach similar to that used by Brown and Spector [14,15] in calculating the energies of excitons and hydrogenic impurities in a cylindrical quantum wire, we chose as our variational wavefunction…”

Effect of the parabolic potential on the binding energy of a hydrogenic impurity in a spherical quantum dot

“…Due to their small sizes these structures present some physical properties that are quite different from those of the semiconductor constituents and hold promise as the basis of a new technology for building smaller devices. The optical and electronic properties of quantum wells (QWs), quantum well wires (QWWs) and quantum dots (QDs) have been the subject of both theoretical and experimental investigations [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. An understanding of the nature of impurity states in semiconductor structures is one of the crucial problems in semiconductor physics.…”

Stark effect of interactive electron–hole pairs in spherical semiconductor quantum dots

“…Other EMA models have been built upon finite potential wells, improving agreement with experimental data for a significant range of QD sizes [17][18][19][20][21]. In addition to spherical clusters, the case of cylindrical shaped micro-crystals has been carefully studied [17,[22][23][24], as well as the case of quantum wires [25,26]. More sophisticated models, which consider non-parabolic valence and/or conduction band(s), have been also developed [27][28][29][30][31].…”
