“…Nevertheless, despite the better performance of the polycrystalline diodes, their QE is lower than the values reported by Fathauer et al 5 for CoSi2. His device shows a QE of almost 1% at ?%=1.35 rim, whereas for our polycrystalline diodes it is 0.37%.…”

The infrared response of polycrystalline and epitaxial CoSi2/Si Schottky diodes with similar silicide thickness has been measured. For the polycrystalline diodes the quantum efficiency is found to be two times higher than for the epitaxial diodes, although both types of diodes present very similar barrier height. The observed improvement is attributed to grain boundary scattering of the excited carriers.

“…The nanoparticles, 10-50 nm in dimensions and lattice-matched to Si, were formed via columnar molecular beam epitaxy and their size can be tailored to support SPP resonances at wavelengths of interest [25]. Embedding nanoparticles in this manner allows detection of infrared radiation (λ 0 = 1-2 μm) via IPE [24,27] because the CoSi 2 nanoparticles form Schottky barriers at all interfaces with the Si, and as an SPP resonance on a nanoparticle decays, it generates hot carriers therein, leading to photocurrent [26]. The nanoparticles may become charged during illumination because they are not contacted to an electrode (i.e., they are "floating").…”

“…Detectors involving metal nanoparticles embedded, e.g., into Si [24][25][26][27] or GaAs [28,29] were among the first investigated. Figure 9.4a shows a sketch of a substrate-illuminated (infra-red) Co/p-Si Schottky diode with CoSi 2 nanoparticles embedded into single-crystalline Si [27].…”

Surface plasmon Schottky detectors combine a structured metal contact that supports surface plasmons with a semiconductor, forming a rectifying metal-semiconductor junction. Internal photoemission occurs in such junctions via the excitation of hot carriers in the metal due to the absorption of surface plasmons therein, leading to photocurrent collected in the semiconductor. The cut-off wavelength of such detectors is determined by the Schottky barrier height, enabling detection below the bandgap of the semiconductor. The metal contact can be structured as a waveguide, grating or antenna on which surface plasmons are supported. Surface plasmon sub-wavelength confinement and field enhancement lead to significant enhancement of the internal photoelectric effect. The operating principles behind surface plasmon detectors based on internal photoemission are reviewed, the literature on the topic is surveyed, and avenues that appear promising are highlighted. IntroductionA surface plasmon-polariton (SPP) is a transverse-magnetic surface wave that propagates along the interface between a metal and a dielectric at optical wavelengths, as a coupled excitation formed from electromagnetic fields coupled to a charge density wave [1]. SPPs are supported on a variety of metal-dielectric structures, including planar arrangements of dielectric and metal films [2], metal gratings [3], and metal nanoparticles such as spheres, islands, rods [4,5], or nanostructured resonators (antennas) [6]. SPPs are also involved in optical transmission through one or many sub-wavelength holes in a metal film [7]. SPPs have interesting and useful attributes such as sub-wavelength confinement, energy
