求鑒定毒性到底有多大
|
|
求各位幫忙鑒定下這個研究方向毒性有多大?適合讀博嗎?前景怎么樣?因為今天一老師說他的同事因為研究As得病了,我很害怕啊。。。求鑒定!具體方向如下: Our main research field is "Spin-Electronics" or "Spintronics", in which we try to utilize the spin degrees of freedom in artificially synthesized materials. We are studying epitaxial growth, structural characterizations, electronic/optical/magnetic/spin-related properties (in particular, spin-dependent transport and mageto-optical properties), and device applications of various new structures. The following are some of the structures and devices we are working on: 1.Ferromagnetic metal / semiconductor hybrid structures 2.III-V based magnetic semiconductors and their heterostructures 3.Group-IV baaed magnetic semiconductors 4.Ferromagnetic nanoparticles / semiconductor hybrid heterostructures 5.Delta doping of magnetic impurities in semiconductor heterostructures 6.New spin transitors (eg. spin-MOSFET) and reconfigurable logic devices 研究的三五族的全是GaAs還有GaMnAs、In神馬之類的,貌似用的方法是MBE什么的,具體的各個器件的解釋太多了,粘貼不上,哪位好心的大哥大姐愿意詳細地講解的,請發(fā)消息給我啊啊啊,關(guān)系到人身安危啊啊啊啊!拜托各位明白人兒啦!! |
