Fig. 11. Scanning electron micrograph (SEM) of a 1-N Vickers indentation in (111) silicon revealing plastically extruded material [64]. Similar extrusions were revealed by TEM in the Berkovich indentations made in (100) Si at ultralow loadings (∼10 mN) [16]. Although isolated diffraction...
这项工作提供了一种替代的光合作用途径,以减轻过量的二氧化碳排放,并有效地从二氧化碳和甘油中产生增值化学物质。 相关工作以《A red-light-powered silicon nanowire biophotochemical diode for simultaneous CO2 reduction and glycerol valorization》为题在《Nature Catalysis》上发表论文。这也是杨培东院士在《Nature Ca...

The structural transition in inner portions of medium-sized silicon clusters has been a puzzle over a decade. By performing extensive search of the "compressing-liquid-silicon" strategy we proposed together with the "stuffing-fullerene" approach, the low-lying structures of Si-n (n = 40-57, ...

Super junction MOSFET的特点n-漂移区存在极性相反的N条和P条间隔堆积,这意味着电场不仅存在于垂直方向,也存在于水平方向。它允许使用掺杂率较高的n-漂移层,因此在维持同样的耐压情况下,Super junction MOSFET能够比平面型的MOSFET大大降低器件的导通电阻。
光电极进行NAD+转化为NADH辅酶是使用太阳能用于活化氧化还原生物催化剂和酶催化合成的方法。但是许多光电极面临着非常低的光电压,导致需要较高的偏压用于制备NADH。 有鉴于此,加州大学伯克利分校杨培东等报道一种较高光电压(435 mV)的n+p Si纳米线(n+p-SiNW...
Preliminary attempts in sintering laser produced silicon carbide have shown, that, due to the nanometric dimension of the powder particles, it is possible to retain the β-SiC low temperature phase even for sintering temperature up to 2150 °C. 1995. 展开 ...
