Comfortable and healthy lighting is a new demand for consumption. What kind of light source is a comfortable and healthy light source? Human beings have lived on Earth for millions of years and are constantly evolving as the living environment changes, but the only constant is the dependence and adaptation to sunlight. Therefore, it can be considered that natural light or sunlight is the most comfortable and healthy light source for human beings. Therefore, when manufacturers introduce health lighting products, they will almost always use the sun as a benchmark, which is similar to sunlight and even better than sunlight. The spectrum of sunlight includes spectral curves of ultraviolet light, visible light, and infrared light, which can be called full spectrum. The natural light full spectrum LED light source means that the proportion of each band in the visible light portion of the LED light source is similar to that of sunlight, and the color rendering index is close

The years go by, our complexion loses radiance, the wrinkles are accentuated, the skin relaxes ... So how to find a smooth skin, a firmer oval or a flawless complexion?The trend towards non-invasive methods is becoming more and more the preference of all those who wish to curb the ills of aging, but who also want to do it gently. So we tested for you radio frequency eye lifting! What is radio frequency? It is a technique based on the emission of very high frequency electromagnetic waves passing through the skin and producing heat in the subcutaneous tissues. This heat induces retraction and collagen production that improves firmness and skin tension. Radio stations frequency is perfect for individuals who wish to combat sagging skin (oblong face, neck, eyescrow's ft, belly, arm ...), to individuals who no more support their cellulite and also the persistent orange peel, to individuals who wish to firm their physiques following a diet but don't want

Frequently used in cosmetics, radio frequency refers to a treatment of the skin through a short wave emission. During its application, the short waves of eye lifting beauty machine generating heat will penetrate the superficial layers of the skin. This heat production brings a beneficial effect, indeed, this technique stimulates the production of fibers, collagen and elastin, it also causes the contraction of existing fibers. This contraction is a source of tension that gives the skin its firmness, a good method to fight against sagging skin. If generally the treatment of eye lifting beauty machine is a touch painful and needs using anesthetic creams, this latest generation is much more effective and much more comfortable. The treatment using the unipolar radiofrequency dermo-controlled doesn't need using anesthetics since it is painless. Additionally for this sweetness, this latest device includes a wider application area. Additionally to some facial treatm

Imagine your smartphone’s battery is dead. Until now, you first must find the charging cable, then connect it to your phone and finally plug it into an outlet. The process works, but it can be a nuisance. Especially if your cable is playing hide and seek or if the jack doesn’t fit the cable. Wireless charging removes the hassle of re-fueling your devices. By using electromagnetic fields to transfer power from a transmitter to a receiver application, it charges your battery without a physical connection. All thanks to a wireless charging power supply. Now compatible devices from a wide range of receiver applications can fuel up cable-free. Currently, inductive or resonant solutions can be used for the following applications: Smartphones and wearables Notebooks and tablets Power tools and service robots, such as vacuum cleaners Multicopters and electric toys Medical devices In-car charging There are many reasons why you should choose wireless cha

In this study, the feasibility of using wafer-bonding technology to fabricate a GaSb semiconductor on GaAs substrate for potentially creating a GaSb-on-insulator structure has been demonstrated. A GaSb wafer has been bonded on two types of GaAs substrates: (1) a regular single crystal semi-insulating GaAs substrate (2) the GaAs wafers with pre-deposited low-temperature amorphous α-( Ga,As ) layers.    The microstructures and interface adhesion studies have been carried out on these wafer-bonded semiconductors. It has been found that the GaSb-on-α-( Ga,As ) wafers have shown enhanced interface adhesion and lower temperature bonding capability.

We propose the growth of GaN on patterned silicon-on-insulator (SOI) substrates , i.e. the GaN-on-patterned-SOI technique. The selective growth is suppressed at the low temperature molecular beam epitaxy (MBE) growth, and GaN nanocolumn are thus epitaxially grown on a silicon substrate and a silicon oxide substrate. The GaN slabs grown on the silicon oxide substrate are totally suspended in space by an association of bulk silicon micromachining and buffered HF etching. The photoluminescence and the reflection results suggest that silicon absorption of the emitted light is eliminated for the freestanding GaN slab, and the reflection losses are reduced at the GaN nanocolumn surface. This work provides a promising way to combine SOI technology with the growth of GaN for producing new optical devices. source:iopscience For more information or other products like GaN Wafer , GaN Substrate , please visit our website: semiconductorwafers.net send us email at angel.

There is a method of controlling nucleation and lateral growth using the three-dimensional (3D) and two-dimensional (2D) growth modes to reduce the dislocation density. We performed 3D–2D-AlN growth on 6H-SiC substrates to obtain high-quality and crack-free AlN layers by low-pressure hydride vapor phase epitaxy (LP-HVPE). First, we performed 3D-AlN growth directly on a 6H-SiC substrate . With increasing V/III ratio, the AlN island density decreased and the grain size increased. Second, 3D–2D-AlN layers were grown directly on a 6H-SiC substrate . With increasing the V/III ratio of 3D-AlN, the crystalline qualities of the 3D–2D-AlN layer were improved. Third, we performed 3D–2D-AlN growth on a trench-patterned 6H- SiC substrate . The crack density was reduced to relax the stress by voids. We also evaluated the threading dislocation density by using molten KOH/NaOH etching. As a result, the estimated edge dislocation density of the 3D–2D-AlN sample was 3.9 × 108 cm−2. s
