    The semiconducting nitrides are a key optoelectronic material, which enabled the development of energy efficient light bulbs based on light emitting diodes (LEDs). Whilst the blue LEDs use in such light bulbs are a tremendously successful technology, nitride LEDs at other wavelengths – from the red to the ultra-violet – suffer from low efficiencies...

    Nitride transistors are increasingly used in high frequency, high voltage, high temperature and high efficiency applications. In the control and conversion of electric power, silicon-based devices are no longer able to meet the demands of industry. However, GaN can endure greater electric fields than silicon, and GaN-based devices can be made with ...

    GaN in its stable wurtzite crystal structure has achieved amazing things in both electronics and optoelectronics. However, the alternative metastable zincblende structure may offer solutions to some of the enduring problems of nitride technology, such as the relatively low efficiency of red, green and amber nitride LEDs. This is because the zincble...

    To improve the performance of GaN-based devices we need to understand their structure and electronic properties on a micro- to nano-metre scale. New techniques are being developed to meet the demands of this unusual semiconductor. An ongoing approach, pioneered by the Cambridge Centre for Gallium Nitride is to combine multiple microscopy techniques...
