傳統電子用電壓製造「閘門」,控制電晶體的「0、1」開關,
進而使其運作,一個小小20 奈米的 A8 晶片,就有高達 20 億個電晶體,
是現代數位世界的基石。

量子力學的方法使電子「旋轉」,進而達到與傳統積體電路相同效果,
但因理論採用磁學性質,多年來都無人製造出實體。

摘錄一段敘述
This is because a splitting the HH and LH bands occurs at the zone
center due to the difference in the energy eigenvalue resulting from
different hole masses.

there is some penetration of the exciton wavefunction into the barrier
material.

Since this binding energy is much larger than the thermal broading,
the exciton resonances are clearly seen in the absorption spectra
even at room temperature.

這是著名的the quantum confined Stark effect (QCSE).

心得:
(E-λ*I)*v=0
可以求出eigenvalue和eigenvector

參考R.Shankar的量子力學,p.32,The Characteristic Equation and Solution
to the Eigenvalue Problem
eq.1.8.7 and eq.1.8.8 and 1.8.9

Although the polynomial is being determined in a particular basis,
the eigenvalue, which are its roots, are basis independent, for they
are defined by the abstract eq.1.8.3,which makes no reference to any
basis.

結論:磁阻=磁動勢/磁通量
