Although organic thin film transistors (OTFTs) made from organic semiconductors are valued for their transparency, flexibility and low cost attributes, their sluggish response time due to slow carrier mobility limits their applications.
Stanford researchers have developed a simple and effective method to sort semiconducting from metallic single walled carbon nanotubes (SWNT). This scalable technique uses semiconducting polymers to wrap around individual semiconducting SWNTs dispersed in a solution.
