Wood semiconductors

Japanese researchers developed a process that brings semiconductors made of wood closer to reality.

The idea of making semiconductors from wood isn’t impossible.  In fact, plant cell walls can conduct electricity when heated to relatively high temperatures under certain conditions.  However, the problem with these cell walls or nanopaper is that burning them can quickly destroy the structure that allows them to conduct electricity.

The new process uses iodine treatment that protects the structure of the nanopaper at elevated temperatures.  This is combined with a controlled drying technique.  The breakthrough allowed the researchers to observe the electrical properties of the nanopaper at selected temperatures.  Soon, semiconductors from wood can be used for practical devices, making way for sustainable electronics.

Are you excited about this innovation?  Will we see future cell phones, computers, and other gadgets operated by semiconductors made of wood?  Please share your thoughts.
