Engineers create world's first transparent transistor

Engineers at Oregon State University have created the world?s first transparent transistor, a see-through electronics component that could open the door to many new products. The discovery ?is a significant development in the context of transparent electronics,? the scientists said in their publication, but pointed out it?s too early to tell what applications may evolve. ?There?s no doubt it will open the door to some interesting new products and businesses, but we?re not sure what all they might be.”
