Wafer-Scale Assembly of Highly Ordered Semiconductor Nanowire Arrays by Contact Printing

Abstract: Controlled and uniform assembly of "bottom-up" nanowire (NW) materials with high scalability presents one of the significant bottleneck challenges facing the integration of nanowires for electronic applications. Here, we demonstrate wafer-scale assembly of highly ordered, dense, and regular arrays of NWs with high uniformity and reproducibility through a simple contact printing process. The assembled NW pitch is shown to be readily modulated through the surface chemical treatment of the receiver substrate, wit… Show more

“…Recently, we have developed a contact printing technology for direct transfer of highly ordered and aligned NW arrays on various receiver substrates with high reproducibility over large areas (29,30). In this approach, a dense ''lawn'' of single crystalline NWs with controlled composition is first grown on a growth substrate by using the vapor-liquid-solid process, followed by the transfer of NWs to a receiver substrate by a directional sliding.…”

“…Here, we demonstrate an all-integrated, heterogeneous nanowire (NW) circuitry, capable of detecting and amplifying an optical signal with high sensitivity and responsivity. By implementing our recently developed contact printing technology (29,30), large arrays of optically active CdSe NWs and high-mobility core/shell Ge/Si NWs are assembled at well defined locations on substrates, and configured as integrated sensor and electronic active components of an all-nanowire circuitry with image-sensing capability.…”

“…44 Since then, Lieber and others have demonstrated the syntheses of a wide range of NW materials, including heterostructures (Figure 4) [45][46][47] with advanced and well-defined functionalities and properties while controllably assembling them into hierarchical structures ( Figure 5) and configuring them for a wide range of applications. [48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66] Properties and Applications. While the material properties of carbon nanotubes are primarily governed by their chirality (and thus, their diameter), for NWs, the properties are tuned by both the diameter and the elemental composition, which adds another handle in controlling functionality.…”

“…54,55 Interestingly, NWs can be assembled as highly ordered arrays by contact printing on unconventional substrates, such as plastic, glass, or paper for high-performance, "printable" macroelectronics ( Figure 5). 56,57 Semiconductor NWs have also been utilized for harvesting solar, mechanical, and thermal energies. 60,[64][65][66] For instance, allinorganic and inorganicϪorganic hybrid solar cells based on individual NWs and NW arrays have been demonstrated as possible routes toward cheap and yet reasonably efficient photovoltaics.…”

“…Procedures developed for contacting large ensembles of randomly positioned nanodevices on a substrate with electron beam lithography have not been published. Other approaches in the literature to place many nanowires in parallel in a controlled way on wafer scale to pre-patterned sites include dielectrophoresis [28][29][30][31][32] and contact printing [33].…”
