不同尺寸分布的自组织In_(0.55)Al_(0.45)As/Al_(0.5)Ga_(0.5)As量子点的静压光谱

在15K测量了不同尺寸分布的In_(0.55)Al_(0.45)As/Al_(0.5)Ga_(0.5)As量子点的静压我致发光，静压范围为0--1.3GPa。常压下观察到三个发光峰，分别来源于不同尺寸的量子点(横向直径分别为26、52和62nm)的发光。它产的压力系数分别为82、94和98meV/GPa,都小于In_(0.55)Al_(0.45)As体材料带边的压力系数，特别是尺寸为26nm的小量子点比In_(0.55)Al_(0.45)As体材料带边小17%，并且压力系数随量子点尺寸的变小而减小。理论计算表明有效质量的增在和Γ-X混合是量子点压力系数变小的主要原因，并得到横向直径为26和52nm的小量子点的Γ－X混合势为15和10meV。根据实验还确定In_(0.55)Al_(0.45)As/Al_(0.5)Ga_(0.5)As量子点系统X能带具有Ⅱ类结构，并且估算出价带不连续量为0.15±0.02。

Observation of the resonant Raman behavior of individual single-walled carbon nanotubes

The different resonant Raman scattering process of single-walled carbon nanotubes (SWNTs) has been found between the Stokes and anti-Stokes sides of the radial breathing modes (RBMs), and this provides strong evidence that Raman spectra of some special diametric SWNTs are in resonance with their electronic transitions between the singularities in the one-dimensional electronic density of states in the valence and conduction bands, and other SWNTs axe beyond the resonant condition. Because of the coexistence of resonant and non-resonant Raman scattering processes for different diametric SWNTs, the relative intensity of each RBM does not reflect the proportion of a particular SWNT.

Three-body force effect on P-3 F-2 neutron superfluidity in neutron matter, neutron star matter, and neutron stars

We investigate the effect of microscopic three-body forces on the P-3 F-2 neutron superfluidity in neutron matter, beta-stable neutron star matter, and neutron stars by using the BCS theory and the Brueckner-Hartree-Fock approach. We adopt the Argonne V18 potential supplemented with a microscopic three-body force as the realistic nucleon-nucleon interaction. We have concentrated on studying the three-body force effect on the P-3 F-2 neutron pairing gap. It is found that the three-body force effect considerably enhances the P-3 F-2 neutron superfluidity in neutron star matter and neutron stars.
