Ning said. single tiny piece of semiconductor material emitting laser light in all colors or in white is desired.
Semiconductors, usually a solid chemical element or compound arranged into crystals, are used widely for computer chips or for light generation in telecommunication systems.
The most preferred light emitting material for semiconductors is indium gallium nitride though other materials such as cadmium sulfide and cadmium selenide also are used for emitting visible colors.
The main challenge, the researchers noted, lies in the way light emitting semiconductor materials are grown
and how they work to emit light of different colors. Typically a given semiconductor emits light of a single colorblue,
green or redthat is determined by a unique atomic structure and energy bandgap. The attice constantrepresents the distance between the atoms.
To produce all possible wavelengths in the visible spectral range you need several semiconductors of very different lattice constants
and energy bandgaps. ur goal is to achieve a single semiconductor piece capable of laser operation in the three fundamental lasing colors.

The most desired solution, according to Ning, would be to have a single semiconductor structure that emits all needed colors.

Organic semiconductor Field Effect Transistors("OFET, "hereafter) using an electroless plating process. By using an electroless gold plating process with silver nanoparticles as a catalyst for an organic semiconductor,
this technology enables the formation in the atmosphere of top contact-type OFET (figure 1)* 2 contact electrodes without the use of a vacuum environment,
this technology realizes the formation of a high-performance OFET as there is little damage to the organic semiconductor,
and the performance of the high-mobility*3 organic semiconductor is affected not. Also, due to the emergence of high-performance n-type semiconductor materials in recent years, more advanced organic electronic devices can now be formed at a low-cost thanks to the simultaneous formation of contact electrodes for p-type and n-type
OFET mixed circuits, for which development is speeding up. For p-type organic semiconductors the contact resistance of the contact electrodes using this technology is 0. 1kiloohm-cm or less,
which is the lowest value currently on record in terms of the contact resistance of organic semiconductor contact electrodes formed in the atmosphere.
The atmospheric formation of a high-performance OFET (Figure 2) with low-contact resistance electrodes and high-mobility that are among the top levels in the world is achieved by combining the merits of this technology with those of high-performance
coating-type organic semiconductors developed by Professor Takeya which can be formed atmospherically. This result enables the atmospheric formation of organic electronic devices with high-speed drives
which is achieved by applying a silver catalyst solution for plating that includes silver nanoparticles to an organic semiconductor crystal, after
This enables the single-process formation of low-contact resistance contact electrodes for p-type organic semiconductors
and n-type organic semiconductors, which facilitate a charge injection from silver (Figure 3). EEJA will announce the research findings relating to this technology at the 62nd Jpan Society of Applied Physics Spring Meeting,
Background to this technology OFET is a transistor that uses an organic semiconductor, which means that-among other characteristics unique to organic materials-it can be formed at low-temperatures,
The high-performance of organic semiconductor materials has progressed rapidly in recent years, and materials are being developed with double-digit increases over the figure that was thought to be the limit for the mobility of organic semiconductors.
The pioneering findings of Professor Takeya's research group make possible the atmospheric formation of high-mobility organic semiconductors,
which is expected to increase the fields of use for organic semiconductors. While there are several methods for the formation of OFET contact electrodes
they all suffer from such issues as requiring a vacuum environment and causing damage to organic semiconductors.
For example, thin film electrodes can be formed uniformly using the vacuum deposition method, but the equipment used to create a vacuum environment is incredibly expensive,
which damages the organic semiconductor, and does not achieve sufficient results as a transistor. This is why
in September 2014, EEJA together with Professor Takeya's research group jointly developed plating-process contact electrode formation technology for p-type organic semiconductors.
In order to stably form electrodes for organic semiconductor crystals, EEJA developed new gold nanoparticles as an electroless plating catalyst.
Also, Professor Takeya's research group developed a coating-type organic semiconductor that could be formed in a short time in the atmosphere with a large-surface thin film with uniform crystal orientation
and a mobility (which is the deciding factor in the performance of semiconductors) that greatly surpasses that of conventional organic semiconductors at 10cm2/Vs or more.
Currently, development is mainly progressing for devices that use p-type organic semiconductors, but the development of all-flexible displays and wearable computers,

the electrified object is referred to as a p-(positive) type organic semiconductor. By injecting a negative charge, the electrified object is referred to as an n-(negative) type organic semiconductor.
The metal that is easier to be injected with a charge varies depending on whether it is a p-type or n-type.*
*2 Top contact-type OFET This is an organic transistor where the contact electrodes are located on the semiconductor crystal.
However, because the electrodes are formed after forming the organic semiconductor crystal, the organic semiconductor is damaged easily, and contact electrodes are difficult to form.*
*3 Mobility This signifies the ease of movement for the charge within the semiconductor. Electronic devices that carry out complex processes require a higher mobility.
Until a few years ago, the mobility of organic semiconductors was generally about 0. 1cm2/Vs, but materials have been developed in recent years with a mobility of 10cm2/Vs or more.*
*4 Printed electronics This is a technology for the atmospheric formation of electronic circuits and devices on substrates using printing technology and so on.##
The Berkeley researchers were able to overcome both these hurdles by forming their grating bars using a semiconductor layer of silicon approximately 120 nanometers thick.
