Abstract

Nanoscale fabrication methods provide a unique approach to synthesize nanoscale materials. Laser-assisted embossing was used to generate close-packed arrays of hemispherical nanowells with zeptoliter (zL) volumes. The volumes of the nanowells were controlled by changing the fluence of the laser, by applying variable pressure between the mold and the substrate, and by growing an amorphous oxide on the patterned silicon. Nanowells with diameters as small as 50 nm were used as reaction vessels for the preparation of simple inorganic salts and semiconducting nanocrystals. Under most growth conditions, individual nanocrystals were formed in individual nanowells.

zeptoliiter烧杯中质量限制生长:一种合成纳米晶体的一般方法

纳米级制造方法为纳米材料的合成提供了一种独特的途径。采用激光辅助压印技术制备了体积为zL的半球形纳米孔阵列。通过改变激光的影响、在模具和衬底之间施加可变压力以及在图案硅上生长非晶氧化物来控制纳米孔的体积。用直径小至50 nm的纳米孔作为反应容器制备简单无机盐和半导体纳米晶体。在大多数生长条件下，单个纳米晶体在单个纳米孔中形成。
