#Scientists grow organic semiconductor crystals vertically for first time Our smartphones, tablets, computers and biosensors all have improved because of the rapidly increasing efficiency of semiconductors.
Since the turn of the 21st century, organic, or carbon-based, semiconductors have emerged as a major area of interest for scientists
because they are inexpensive, plentiful and lightweight, and they can conduct current in ways comparable to inorganic semiconductors,
which are made from metal-oxides or silicon. Now, materials scientists from the California Nanosystems Institute at UCLA have discovered a way to make organic semiconductors more powerful and more efficient.
Their breakthrough was in creating an improved structure for one type of organic semiconductor a building block of a conductive polymer called tetraaniline.
The scientists showed for the first time that tetraaniline crystals could be grown vertically. The advance could eventually lead to vastly improved technology for capturing solar energy.
Tetraaniline is a desirable material for semiconductors because of its particular electrical and chemical properties, which are determined by the orientation of very small crystals it contains.
because vertical crystals can be packed more densely in the semiconductor, making it more powerful and more efficient at controlling electrical current. hese crystals are analogous to organizing a table covered with scattered pencils into a pencil cup,
