Concerns over possible toxicities of conventional metal-containing quantum dots have
inspired growing research interests in colloidal silicon nanocrystals (SiNCs), or silicon …

As the most fundamental material for microelectronics, silicon (Si) has bourgeoned in the
past more than half a century. However, given the indirect bandgap of Si, the use of Si in …

We develop a fast-response and flexible nanocrystal-based humidity sensor for real-time
monitoring of human activity: respiration and water evaporation on skin. A silicon …

Localized surface plasmon resonance (LSPR) of doped Si nanocrystals (NCs) is critical to
the development of Si-based plasmonics. We now experimentally show that LSPR can be …

We present a novel synthesis of ligand-free colloidal silicon nanocrystals (Si-NCs) that
exhibits efficient photoluminescence (PL) in a wide energy range (0.85–1.8 eV) overcoming …

We developed a broadband dielectric–metal hybrid nanogap resonator composed of a
silicon nanoparticle (Si NP) and gold (Au) flat surface. We fabricate the nanogap resonator …

The ability to incorporate a dopant element into silicon nanocrystals (NC) and quantum dots
(QD) is one of the key technical challenges for the use of these materials in a number of …

Colloidal heavily doped silicon nanocrystals (Si NCs) exhibiting tunable localized surface
plasmon resonance (LSPR) are of great interest in cost-effective, solution-processed …

Size dependence of the boron (B) acceptor and phosphorus (P) donor levels of silicon (Si)
nanocrystals (NCs) measured from the vacuum level was obtained in a very wide size range …

Silicon nanocrystals (Si NCs) are intensively studied for optoelectronic and biological
applications due to having highly attractive features such as band engineering. Although …
