High-speed bolometric detector based on a graphitized layer buried into bulk diamond
Abstract
A bolometer based on a buried graphitized layer built into a diamond matrix is described. The bolometer was formed by ion implantation on IIa-type diamond plate with subsequent annealing. The R( T) characteristic of the bolometer was linear with a resistance temperature coefficient -0.06 Ω/K. The bolometer response to a nitrogen laser pulse radiation was studied for temperatures 300 and 90 K. The bolometer operating speed was less than several nanoseconds. Calculation of the temperature distribution dynamics in the layered structure was carried out by the solution of a system of linear thermal conductivity equations.
