An avalanche photodiode includes: a first contact layer; a light absorbing layer located on the first contact layer and having a multi-quantum well structure; a first electric field control layer located on the light absorbing layer; and a carrier multiplication layer located on the first electric field control layer. 0000001107 00000 n out of the active area of the APD. This structure provides ultra high sensitivity at 400-1000 nm. The most critical device parameters of APD include the avalanche breakdown voltage and dark current. 0000001555 00000 n Nano- multiplication- region avalanche photodiodes (NAPDs), and imaging arrays of NAPDs integrated with complementary metal oxide/semiconductor (CMOS) active-pixel-sensor integrated circuitry, are being developed for applications in which there are requirements for high-sensitivity (including photoncounting) detection … This structure irremediably suffers from premature edge breakdown. • Se concentrer sur les entreprises clés du marché Photodiode à avalanche APD pour définir, décrire et examiner les ventes, la part de marché, le volume, la valeur, le développement récent et le paysage de la concurrence sur le marché. cause a fraction of them to become part of the photocurrent. The photodiode reach-through structure is of an n PLU-p-(pi) - p + type with an under-contact ring and a channel stopper. Avalanche photodiodes (APDs) are key optical receivers due to their performance advantages of high speed, high sensitivity, and low noise. 0000011144 00000 n structure avalanche photodiodes,” IEEE Trans. APDs. This process is known as avalanche 0000012164 00000 n Avalanche photodiode is basically a PN junction diode which operates in the avalanche breakdown region.
