GROUP IV Semiconductor patents

I did a search and found these (will they render CNT, SED, LCD, plasma, OLED to the garbage heap?):

Results of Search in US Patent Collection db for:
AN/"Group IV"

Hits 1 through 2 out of 2

1 7,122,842 Full-Text Solid state white light emitter and display using same
2 7,081,664 Full-Text Doped semiconductor powder and preparation thereof


1) includes a BLU embodiment as well as a display embodiment.

This Japanese patent also looks interesting:
United States Patent 6,897,604
Koshida May 24, 2005

Method of generating ballistic electrons and ballistic electron solid semiconductor element and light emitting element and display device


A method of generating ballistic electrons with a high controllability by applying an electric field to a nano-structure micro-crystal layer or a semi-insulating layer of a semiconductor to generate ballistic electrons or quasiballistic electrons by a multiple-tunnel effect; and a semiconductor device used in this method and provided with a practical material constitution.

Inventors: Koshida; Nobuyoshi (Tokyo, JP)
Assignee: Japan Science and Technology Corporation (Saitama, JP)
