Lanthanum hexaboride (LaB6) nanowires have attracted much attention due to their outstanding physical properties. In order to enhance the developments of LaB6 nanowires, it is essential to study the field emission (FE) properties of LaB6 nanowires in different environments. Here, we investigate the effect of oxygen (O2) on the FE behaviors of LaB6 nanowires. And it is found that the oxygen content...
SmB6 is believed as an ideal candidate for FE applications because of their unique properties. Up to date, the effect of image potential on the field emission (FE) behaviors of one-dimensional nanostructures is still unclear in experiments, and thus it becomes a challenging issue for the researchers. In this paper, the effect of image potential on FE properties of SmB6 nanowires are detailed studied...
Controlled synthesis of ultra-long AlN nanowire arrays in different growth density has been successfully realized by direct nitridation of Al powders for the first time. These AlN nanowires have an average diameter of about 100 nm and their mean length is over 50 μm. All the synthesized ultra-long nanowires are pure single crystalline h-AlN structures with the growth orientation of [0001]. We propose...
