Density-of-statesDark conductivity and photoconductivity in AlxGa1−xN (x=0.025, 0.18) films prepared by MOCVD on a sapphire substrate with a GaN bottom layer have been investigated. In the temperature range 300–500 K, the barrier at the heterostructure interface appears to play an ...
1.The electronic energy spectrum and density of states (DOS) for several simple ring copolymers have been studied by using a tight-binding calculation.针对由小带隙的聚乙炔和大带隙的苯作为聚合物单体的聚合物的几种简单环状模型,采用紧束缚近似计算方法,研究了它们的电子能谱和态密度特征,并考虑到环状结...
Obtaining ρ energy (E) is accomplished through what is referred to as a density-of-states calculation. We will illustrate this below and in later parts of the chapter. Apart from giving us a better handle on the state distribution of our system, the resulting DOS is important for many ...
1.The distribution oflocal density of states(LDOS) in quasiperiodic photonic crystal(QPC) and the total density of states(DOS) are studied.本文研究了准晶光子晶体的局域态密度和全态密度。 2.the density of states andlocal density of statesof the two-dimensional photonic crystal composed of air cy...

1(A) and (B), the ultrathin TiO2 flake exhibits obviously enhanced density of states (DOS) at the conduction band edge as compared to its bulk counterpart (as represented by red arrow in figure), which could be further demonstrated by the corresponding distribution of charge density in Fig....
Density of States refers to the function that shows the distribution of energy levels (above the ground state energy) as a function of the energy, with increasing BCS interaction strength. AI generated definition based on:Surface Science Reports,2007 ...
