Purpose and goal
The purpose was to study boron doped cubic silicon carbide as potential solar cell material. The goal was to develop a growth method for cubic silicon carbide, introduce boron and study the optical transitions which could verify that it is reasonable to develop cubic silicon carbide as potential solar cell material.
Expected results and effects
We observed the optical transitions in doped cubic silicon carbide. The expect impacts are that the material may be further developed as bulk material, as well as being promising as solar cell material. Both these paths may lead to industrial activities.
Planned approach and implementation
The project plan was to explore a growth process to achieve cubic silicon carbide in as high structural quality as possible, and with a reproducible process. From this process window we doped the cubic silicon carbide with boron in two ways: one during growth and one by ion implantation. Both routes demonstrated optical transitions, and thereby a confidence in the result.
