Abstract: As one branch of spintronics, diluted magnetic semiconductors DMSs are extensively investigated due to their fundamental significance and potential application in modern information society. Alternatively, the discovery of a new generation DMSs with independent spin and charge doping, such as Ba,K Zn,Mn 2 As 2 briefly named BZA , attracted considerable attention due to their unique advantages in physical properties and heterojunction fabrication. The prospective of new type of DMSs with independent spin and charge doping is briefly discussed.

Have one ever seen a semiconductor that can issue two-color lasing lines? The diluted magnetic semiconductor DMS can do this. This finding opens a way to understand the collective behaviour of spin-coupled excitons in DMS and to find novel applications in the spin-related quantum technology. However, no one has ever detected dual lasing lines with large-separation issuing from one semiconductor structure at the same time because there are no different dense excitons of very different energy values except those semiconductor nanostructures in the optical cavity [ 4 , 5 ]. In contrast to the photon binding in an optical cavity, the local spontaneously ferromagnetic moments or coupled spins in a DMS structure supplied another choice to bind excitons to the collective EMP formation for single-mode lasing [ 6 , 7 ].

Can we build materials that show properties of both ferromagnets and semiconductors at room temperature? Magnetic semiconductors are semiconductor materials that exhibit both ferromagnetism or a similar response and useful semiconductor properties. If implemented in devices, these materials could provide a new type of control of conduction. Whereas traditional electronics are based on control of charge carriers n- or p-type , practical magnetic semiconductors would also allow control of quantum spin state up or down. While many traditional magnetic materials, such as magnetite , are also semiconductors magnetite is a semimetal semiconductor with bandgap 0.

In , a seminal study predicted ferromagnetism above room temperature in diluted magnetic semiconductors and oxides, fuelling.

Каждый шаг Стратмора был рассчитан самым тщательным образом. Строя свои планы, Стратмор целиком полагался на собственный компьютер.
