Answer True for correct sentences and False for incorrect sentences 1- The diffusion current is produced as a result of a variation in the concentration of charge carriers, as the charge carriers move from places with high concentration to places with low concentration under the influence of the applied electric field 2- The silicon atom (14) covalently bonds with the carbon atom (6) to form a Sic. crystal 3- To achieve the process of electrical conduction in semiconductor materials, foreign elements are introduced into the pure crystal by a process known as grafting 4- Current can only pass through the adjusting junction if the work function of the metal is greater than the work function of the semiconductor.
