Reach through apd
WebA reach-through APD of a 130 µm thickness can potentially detect soft X-rays below 20 keV with efficiencies greater than 10%. The signal amplification in the APD devices has a good advantage of detecting soft X-rays even at room temperature or at lightly cooled environment[11,12]. Figure 3 presents

WebOct 7, 2024 · The reach-through avalanche photodiode (RAPD) is composed of a high-resistivity p-type material deposited as an epitaxial layer on a pt (heavily doped p-type) substrate. A p-type diffusion or ion implant is then made in the high-resistivity material, followed by the construction of an nt (heavily doped n-type) layer.
