Current crowding problem generally occurs in conventional III-nitride light emission diodes (LEDs) due to design geometry. This problem give rises to unequal heating and unequal light emission from LED dice. Current crowding problem can be reduced by using multi-finger design, where active area of LED device is divided into two portions and thus total emission from device increases. By delta doping we can reduce, current crowding problem in conventional III-nitride LEDs design. Current crowding problem vanishes almost in multi-fingered design with delta doped layer..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
