Introduction Developments in solid state lighting (SSL) in recent years have led to an extensive increase in the driving current of light emitting diodes (LEDs). Although corresponding increases in light output and efficiency has also been noted, current lighting design applications require the implementation of multiple diodes to allow its utilization in universal lighting … [Read more...]
Thermal Load Board Design Considerations
INTRODUCTION A Thermal Load Board (TLB) is a hardware tool used to simulate an actual application board, for example - computer motherboard, blade server board, handheld device main logic board, etc. Mounted on the TLB are a variety of heat source simulators that allow heat flux generation in a manner that closely approximates real semiconductor devices and other components … [Read more...]
New High-Efficiency Thermoelectric Air Conditioner
TECA Corporation has introduced the AHP-6200 family of thermoelectric air conditioners. The AHP-6200 air conditioners provide cooling performance up to 5,200 BTU/hr in the 240 VAC configurations. Each system includes TECA’s Eco-Mode temperature control design that limits active cooling when not needed, reducing total power consumption by up to 75 percent. The AHP-6200 air … [Read more...]
Semiconductors Grown on Graphene May Change Industry
CrayoNano AS, in cooperation with the Norwegian University of Science and Technology (NTNU), has introduced GaAs nanowires grown on graphene, a patented hybrid material with competitive properties. The patented method of growing semiconductor nanowires on atomically thin graphene uses MBE (Molecular Beam Epitaxy) to grow the nanowires and offers excellent optoelectronic … [Read more...]
Single Electron Diode May Control Heat Flow in Tiny Future Electronics
As the scale of electronic devices and their components continues to shrink, researchers at Aalto University in Finland are re-examining options for fine-tuning control of the heat generated by electronic components. Doctoral student Tomi Ruokola, in cooperation with researcher Teemu Ojanen of O.V. Lounasmaa Laboratory, has developed a single-electron diode that allows heat to … [Read more...]
