"control the position of the light emission through rational changes to material composition in active layer... fabricated three almost identical LECs in terms of materials, but with clearly distinct efficiencies differing up to 60%... achieved through chemical changes to... ion-transporter molecule... compound that helps ions move within active layer... modify capability of the electronic charges to travel through the material... effectively changes... position... within... active layer and... from where the light is generated"
