Avalanche Photodiode (APD) Animation

This animation describes about an electronic device called Avalanche Photodiode (APD). The device is used to detect visible light by calculating the penetration depth of light, the concentration of its building block (layers) and the effect of dead space. The design of this APD device consists of five layers, namely p1+  layer, pi layer, p2+ layer, n layer and n+ substrate layer, with two regions of electric field, the drift region and the multiplication region (MR). The design takes advantage of the electric field with a range of 1.75 x 105 – 6.40 x 105 V cm-1 at the MR to cause avalanche phenomena.

Jeroning Ancak Saji (read je – ro – nïng än – cäk sä – jï) was the first yard of the palace. There were 4 units of Bale (read Bä – lé) here, 1 unit of well, and 1 unit of high building at south-west Corner called Panggungan (read päng – gung – än). The Panggungan was equipped with some steps made from stone. The King or Cokorda (read Co – kor- de) usually went to Panggungan in the evening to watch the cockfighting, and the people who pass the road. The position was very strategic because it was located at the corner of the cross road to Kesiman, Sanur, Sesetan and Pamecutan. It’s also near from marketplace. So, at that time, Panggungan was one of many favourite places for Cokorda Denpasar to visit.
