In the present work we have measured the forward bias current-voltage (I-V) characteristics of AlGaInP based heterostructures red light emitting diode over a wide temperature range from 350 K to 77 K. The forward I-V characteristics show two distinctive regions below and above roughly 1.75 Volt marked by two different slopes, virtually insensitive to variation of temperature, which seems to suggest that the carrier transport process has complex character and there exist various tunneling mechanisms. The semilog plot of I-V curves exhibit two distinct, low and medium bias regions and the corresponding characteristic energies seem to suggest that there exist probable carriers which are electron and heavy hole respectively that undergoes change with bias voltage. This insight together with the data generated in the investigation will be helpful for device application..

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.
