Optoelectronic device substrates

Materials Today, 2001
During recent years, the market for optoelectronic devices has grown rapidly. The major growth segments in the non-communication optoelectronic market are expected to be light-emitting diodes (LEDs) with revenues of $2.1 billion today reaching $3.2 billion in 2003 and lasers increasing from $1.0 billion to $2.1 billion in 2003. In particular, the group
