Silicon has long been established as the material of choice for the microelectronics industry.
This is not yet true in photonics, where the limited degrees of freedom in material design …

Third-generation approaches to photovoltaics (PVs) aim to achieve high-efficiency devices
but still use thin-film, second-generation deposition methods. The concept is to do this with …

The tremendous interest in nanoscale structures such as quantum dots (zero-dimension)
and wires (quasi-one-dimension) stems from their size-dependent properties. One …

The concept of third generation photovoltaics is to significantly increase device efficiencies
whilst still using thin film processes and abundant non-toxic materials. This can be achieved …

Silicon dominates the electronics industry, but its poor optical properties mean that III–V
compound semiconductors are preferred for photonics applications. Photoluminescence at …

Silicon quantum dots (SiQDs) hold great promise for many future technologies. Silicon is
already at the core of photovoltaics and microelectronics, and SiQDs are capable of efficient …

In the 1990s, nanoparticles and quantum dots began to be used in optical, electronic, and
biological applications. Now they are being studied for use in solid-state quantum …

A variety of silicon-based nanostructures with dimensions in the 1–5 nm range now emit
tunable photoluminescence (PL) spanning the visible range. Achievement of high …

Tandem PV cells–with their increased efficiency due to a multi-band gap approach–usually
involve expensive materials and fabrication. Thin film approaches, with an engineered …

The overlap of the principal luminescence band of the erbium ion with the low-loss optical
transmission window of silica optical fibres, along with the drive for integration of photonics …
