Measurement of minority-carrier diffusion lengths using wedge-shaped semiconductor photoelectrodes
Measurement of the photocurrent as a function of the thickness of a light absorber has been shown herein both theoretically and experimentally to provide a method for determination of the minority-carrier diffusion length of a sample. To perform the measurement, an illuminated spot of photons with an energy well above the band gap of the material was scanned along the thickness gradient of a we...
متن کاملLong minority carrier diffusion lengths in bridged silicon nanowires.
Nanowires have large surface areas that create new challenges for their optoelectronic applications. Lithographic processes involved in device fabrication and substrate interfaces can lead to surface defects and substantially reduce charge carrier lifetimes and diffusion lengths. Here, we show that using a bridging method to suspend pristine nanowires allows for circumventing detrimental fabric...
متن کاملEFFECT OF CRYSTAL DEFECTS ON MINORITY CARRIER DIFFUSION LENGTHS IN 6H Sic
Minority-carrier diffusion lengths in n-type 6H-SIC were measured using the planar electron-beam induced current (EBIC) technique. Experimental values of electron beam current, EBIC, and beam voltage were obtained for n-type SIC with a carrier concentration of 1.7E17 ~ m ~ . This data was fit to theoretically calculated diode efficiency curves, and the diffusion length and metal layer thickness...
متن کاملMeasurement of minority carrier lifetimes in semiconductors
The bulk lifetimes of minority ,carriers in n-type l :germanium, in both n and p-type silicon and in n-type magnesium germanide have been investigated at room temperature. The sample was illuminated with periodic light ·flashes produced by a spark gap. The transient change in conductance of the sample after illumination gave the lifetime. In germanium and silicon the measured bulk lifetimes had...
متن کاملA CMOS Reaction-diffusion Device Using Minority-Carrier Diffusion in Semiconductors
We propose a CMOS device that is analogous to the reaction–diffusion system, a chemical complex system that produces various dynamic phenomena in the natural world. This electrical reaction–diffusion device consists of an array of pn junctions that are operated by CMOS reaction circuits and interact with each other through minority-carrier diffusion. Computer simulations reveal that the device ...
