2. in this paper, the continuity of the wavefunction and of its derivative divided by the band - mass can be satisfied and the number of the terms is small when calculating the energies of the single electron in a square quantum wire with finite barriers, then this wavefunction can also be selected as the envelope function in studying the impurity states and the excitons in the square quantum wires with finite barriers
2 .由於本文所取波函數滿足波函數的連續性條件和粒子流的守恆條件,並且計算有限深方形量子線中單電子的能量時需要展開的項數較少,故此波函數也可選為有限深方形量子線中雜質態、激子等問題的包絡函數。The first two kinds of wavefunctions are simple formally, but there must be error of the numerical values of some physical magnitudes because there is a trouble with the continuity of the function and of its derivative divided by the band - mass at the boundaries. though the third kind of wavefunction can satisfy the continuity of the function and of its derivative divided by the band - mass, the number of the terms is so large that it is difficult to calculate the physical magnitudes in the single quantum wire
前兩種波函數形式比較簡單,但由於在邊界處波函數的河北師范大學碩士學位論文連續性條件和粒子流的守恆條件存在問題,這必將對某些物理量的計算產生影響;第三種波函數在邊界處滿足波函數的連續性條件和粒子流的守恆條件,但是對于單量子線需要展開的項數很多,計算量太大。In 1985, takeshi kodama et al. [ 12 ] expressed the wavefunction as the combination of the function of the single electron in a one - dimensional square well with the finite barrier to calculate the binding energies of the exciton. this form does n ' t satisfy the continuity of the function and of its derivative divided by the band - mass
1985年, takeshikodama等人在計算激子的束縛能時把單電子的波函數( x , y )取為一維有限深方形量子阱中波函數的乘積,這種取法在邊界上不滿足波函數的連續性條件及粒子流( 1 / m ~ * ) ' ( x , y )的守恆條件。[ 5 ] expressed the wavefunction in terms of a two - dimensional fourier series. this form can satisfy the continuity of the function and of its derivative divided by the band - mass. but the number of the terms is so large that it is difficult to calculate the physical magnitudes in the single quantum wire
1996年, s . gangopadhyay等人將波函數用二維傅立葉級數展開,這種取法滿足波函數的連續性條件及粒子流( 1 / m ~ * ) ' ( x , y )的守恆條件,但是當考查單量子線時,需要展開的項數很多,計算量很大。This paper has studied the wavefunction expanded in terms of the two - dimensional harmonic oscillator eigenfunction through calculating the energy of the ground state, the energy of the first excited state and the oscillator strength in a square wire with finite barriers and studied its application in these fields. the most remarkable advantage of this wavefunction is that it can satisfy the continuity of the function and of its derivative divided by the band - mass and it is convenient to calculate some physical magnitudes because the number of the terms is small
本文通過計算有限深方形量子線中單電子的基態能、第一激發態能和振子強度研究了以二維諧振子本徵函數為基展開的波函數以及它在這些問題中的應用,此波函數的顯著優點是:在邊界處滿足波函數的連續性條件和粒子流的守恆條件,並且展開項數少,計算方便。There were troubles in the continuity of the function and of its - derivative divided by band - mass on the boundary. in the theoretical calculation, the wave function is relative to the physical properties of the impurity greatly, the envelop function f ( x, y ) is expanded in terms of the one - dimensional linear harmonic oscillator function in this paper. it satisfies the continuity of the function and of its - derivative divided by the band - mass, so it improves the precision of the function and binding energy
與以往工作不同的是,以前選用的x , y方向電子的包絡函數f ( x , y )是一維有限深量子阱中波函數的乘積,在邊界上波函數的連續性和粒子流的守恆條件存在問題;而在理論計算中,波函數的選取與雜質的物理性質有密切關系,本文選取的電子的包絡函數是用一維線性諧振子的波函數展開而成的,在邊界上能夠同時滿足波函數的連續性及粒子流( 1 / m ~ * ) f ' ( x , y )的守恆條件,從而使得波函數和束縛能的精確度得到了改進。分享友人
