The tip expansion due to laser illumination is an important issue for the development of laser-assisted scanning tunneling microscope (STM).In this letter,the thermal expansion of an STM tip induced b
Current information technology includes information procession and information storage which are carried out by charge-based devices and magnetic material respectively.To efficient manipulate the orie
Ferromagnetic semiconductor (Ga,Mn)As has attracted great attention for both fundamental physics and potential applications since its discovery in 1990s[1].Most attractive properties of (Ga,Mn)As resu
High quality Co doped ZnO thin films are grown on single crystalline AL2O3 (0001) by oxygen plasma assisted molecular beam epitaxy.Micro-Raman measurements were performed to study the influence of Co
Semiconductor spintronics is expected to one of the potential technologies which can outperform the conventional semiconductor devices.An important hurdle in this field is the inefficient injection of
