MicroLink Devices has demonstrated state-of-the-art performance-per-area for flexible, epitaxial lift-off (ELO) three junction (3J) inverted metamorphic (IMM) solar cells. Half-wafer cells with an area of 74.4 cm2 were measured to have an AM0 efficie

Surface plasmon polariton (SPP) propagation in chemically synthesized gold nanobars was investigated using scanning transient absorption microscopy. The SPP propagation lengths were correlated to the size and shape of the nanobars, which were determi

Single crystal, micrometer-sized nanoplates were formed by reducing Au(III) in the presence of surfactants using a modified polyol protocol. The shapes of the plates range from triangular to hexagonal. The nanoplates have {111} surfaces with an avera

Semiconductor nanostructures produced by wet chemical synthesis are extremely heterogeneous, which makes single particle techniques a useful way to interrogate their properties. In this paper the ultrafast dynamics of single CdTe nanowires are studie

Epitaxial lift-off (ELO) is a process technology that can enable substantial performance enhancement and cost reduction for epitaxially grown III–V devices. [1]–[4] In particular, GaAs-based inverted metamorphic multijunction (IMM) solar cells ar

Transient absorption microscopy is used to examine the breathing modes of single gold nanowires in highly viscous liquids. By performing measurements on the same wire in air and liquid, the damping contribution from the liquid can be separated from t

The surface plasmon polariton (SPP) modes of gold nanobars (nanowires with rectangular dimensions) have been investigated by scanning pump–probe microscopy. In these experiments the nanobars were suspended over trenches cut in glass coverslips, and

International audience; The lifetimes of the acoustic vibrations of metal nanostructures depend sensitively on the properties of the environment, such as the acoustic impedance and viscosity. In order to accurately study these effects, they have to b
