Herbert Kroemer, Nobel winner who developed laser tech, dies at 95

#Herbert #Kroemer, a Nobel Prize-winning physicist who spearheaded the development of a new kind of semiconductor, leading to advances at the heart of everything from bar-code scanners, CD players and cellphones to satellite communications and fiber-optic networks, died March 8 at 95.

His death was announced by the University of California at Santa Barbara ( #UCSB ), where he had been on the faculty for nearly 50 years.

A statement from the school’s chancellor, Henry T. Yang, did not say where or how he died but credited Dr. Kroemer with “transforming UC Santa Barbara into a leader in engineering and #materials #science.”

A German-born researcher with a thick white beard and heavy skepticism of scientific authority, Dr. Kroemer was awarded a share of the #Nobel #Prize in #physics in 2000 for developing #semiconductor #heterostructures, layered devices that proved foundational to advanced lasers and high-speed transistors.

He shared his half of the prize with the Russian physicist Zhores #Alferov, who worked independently but in parallel to develop the devices; the other half went to Jack #Kilby, a researcher at Texas Instruments who played a central role in the invention of the integrated circuit, or microchip
