Controlling The Crystal Structure Of Gallium Oxide
A simple method that uses hydrogen chloride can better control the crystal structure of a common semiconductor and shows promise for novel high-powered electronic applications. The electronic components used in computers and mobile devices operate at relatively lower power. But high-power applications, such as controlling electrical power grids, require alternative materials that can cope with […]
The Raw Power Of Human Motion
Autonomy is a much-anticipated feature of next-generation microsystems, such as remote sensors, wearable electronic gadgets, implantable biosensors and nanorobots. KAUST researchers led by Husam Alshareef, Jr-Hau He and Khaled Salama have developed small standalone devices by integrating maintenance-free power units that produce and use their own fuel instead of relying on an external power source¹,².

Marine Exploration Sensing With Light And Sound
Oceanic sensor networks that collect and transmit high-quality, real-time data could transform our understanding of marine ecology, improve pollution and disaster management, and inform the multiple industries that draw on ocean resources. A KAUST research team is designing and optimizing underwater wireless sensor networks that could vastly improve existing ocean sensing equipment. “Currently, underwater sensors […]
Innovative Diode Design Used Ultrafast Quantum Consulting To Harvest Infrared Energy From The Equipment
Most sunlight striking the Earth is absorbed by its surfaces, oceans and atmosphere. As a result of this warming, infrared radiation is emitted constantly all around us-estimated to be millions of Gigawatts per second. A KAUST team has now developed a device that can tap into this energy, as well as waste heat from industrial […]
Cleaning Nanowires To Get Out More Light
A technique for reducing the loss of light at the surface of semiconductor nanostructures has been demonstrated by scientists at KAUST. Some materials can efficiently convert the electrons in an electrical current into light. These so-called semiconductors are used to create light-emitting diodes or LEDs: small, light, energy-efficient, long-lasting devices that are increasingly prevalent in […]
