Typical electron mobility for Si at room temperature (300 K) is 1400 cm2/ (V·s) and the hole mobility is around 450 cm2/ (V·s).
Very high mobility has been found in several low-dimensional systems, such as two-dimensional electron gases (2DEG) (3,000,000 cm2/(V·s) at low temperature), carbon nanotubes (100,000 cm2/(V·s) at room temperature) and more recently, graphene (200,000 cm2/ V·s at low temperature). Organic semiconductors (polymer, oligomer) developed thus far have carrier mobilities below 10 cm2/(V·s), and usually much lower.

Famous quotes containing the word examples:
“There are many examples of women that have excelled in learning, and even in war, but this is no reason we should bring ‘em all up to Latin and Greek or else military discipline, instead of needle-work and housewifry.”
—Bernard Mandeville (1670–1733)
“In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
—Michel de Montaigne (1533–1592)
“No rules exist, and examples are simply life-savers answering the appeals of rules making vain attempts to exist.”
—André Breton (1896–1966)
