[交流] 纳米牛人Lieber的一篇综述Semiconductor nanowires

Semiconductor nanowires
J. Phys. D: Appl. Phys. 39 (2006) R387–R406
Abstract
Semiconductor nanowires (NWs) represent a unique system for exploring
phenomena at the nanoscale and are also expected to play a critical role in
future electronic and optoelectronic devices. Here we review recent
advances in growth, characterization, assembly and integration of
chemically synthesized, atomic scale semiconductor NWs. We first
introduce a general scheme based on a metal-cluster catalyzed
vapour–liquid–solid growth mechanism for the synthesis of a broad range of
NWs and nanowire heterostructures with precisely controlled chemical
composition and physical dimension. Such controlled growth in turn results
in controlled electrical and optical properties. Subsequently, we discuss
novel properties associated with these one-dimensional (1D) structures such
as discrete 1D subbands formation and Coulomb blockade effects as well as
ballistic transport and many-body phenomena. Room-temperature
high-performance electrical and optical devices will then be discussed at the
single- or few-nanowire level. We will then explore methods to assemble
and integrate NWs into large-scale functional circuits and real-world
applications, examples including high-performance DC/RF circuits and
flexible electronics. Prospects of a fundamentally different ‘bottom-up’
paradigm, in which functionalities are coded during growth and circuits are
formed via self-assembly, will also be briefly discussed.
