LEDs are becoming increasingly popular in various fields of the electronics industry: they can be used inside digital clocks, for street illumination applications, to send information and in large-size television screens and computer monitors.

LEDs are similar to incandescent light bulbs but they differ from them as they do not have a filament and therefore they do not get particularly hot and do not become unusable after a certain period of time due to filament burn out.

Different from incandescent light bulbs, LEDs are illuminated uniquely by the movement of the electrons in a semiconductor material.

Such important characteristics, coupled with electricity consumption which is lower than that of incandescent light bulbs make them viable as their potential replacement.

The widespread adoption of LEDs has so far being hindered by a series of factors, the main ones being the relatively high price and lower light output compared with traditional incandescent light bulbs.

GaN deposition is one of the most promising techniques to improve the light output of LEDs and involves the deposition of a thin GaN epitaxial layer on a patterned sapphire substrate (PSS).

The service offered includes the deposition by MOCVD of undoped GaN and of n- or p- doped GaN for high-quality highly-ordered crystalline layers up to 5µm of thickness.

  • AngelTech Live III: Join us on 12 April 2021!

    AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

    Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

    2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

    We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

    We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

    Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

    Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

    So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
