Pixel definitions in a porous silicon quantum dot radiation detector

摘要

The imaging module 114 of the imaging system is interlaced with a first column 208, a contact surface 210 on the opposite side of the first side, and a silicon column 212 configured to extend from the first side to the contact side of the silicon column A porous silicon film having columnar holes 214 and 502 is provided extending from the first side to the contact side surface.The imaging module further includes a quantum dot 118 in a column like hole.The imaging module further includes a metal pad 120 electrically coupled to the silicon column of the porous silicon film.The quantum dots in the columnar holes are electrically isolated from the metal pad.The imaging module further comprises a substrate 122 having a conductive pad 204 electrically communicating with the metal pad defining the pixel.
