Substrateless transferable surface plasmon devices realized by suspended nano-thin film

Abstract

In this study we take the surface plasmon nanolaser as the main research target we used zinc oxide nanowire as the gain medium and spread the nanowires on a 150nm suspended metal film with 5nm alumina as the insulator layer to realize the semiconductor-insulator-metal (SIM) structure To effectively reduce heat accumulation we remove the substrate to get a suspended nano-thin film When the devices are in contact with air it can reduce the heat by the flowing air thereby lowering the laser threshold Through experiments we have confirmed that suspending the film can effectively reduce the laser threshold (the minimum threshold can be reduced to 10μW) and increase the operating temperature to 90°C
