Breakthrough for solar cell efficiency Posted: 25 Oct 2013 11:31 AM PDT Scientists have just revealed the fundamental aspect of a new approach to growing InGaN crystals for diodes, which promises to move photovoltaic solar cell technology toward record-breaking efficiencies.

Nanoscale engineering boosts performance of quantum dot light emitting diodes Posted: 25 Oct 2013 10:53 AM PDT Dramatic advances in the field of quantum dot light emitting diodes could come from recent work. Quantum dots are nano-sized semiconductor particles whose emission color can be tuned by simply changing their dimensions.

Physicists observe the formation of a many-body system in experiment Posted: 25 Oct 2013 06:18 AM PDT How large does a group of particles have to be to render moot its exact number of particles? In experiments using ultracold atoms, physicists succeeded in observing the transition to a many-body system well described by an infinite number of particles. In philosophy, this problem is known as the sorites paradox. The essential question is when a collection of elements forms a "heap."

Physicists aim to make transition to quantum world visible Posted: 25 Oct 2013 06:18 AM PDT Theoretical physicists have developed a mathematical model for a type of microscopic test lab that could provide new and deeper insight into the world of quantum particles. The new test system will enable the simultaneous study of one hundred light quanta (photons) and their complex quantum mechanical relationships ("quantum entanglement") – a far greater number than was previously possible. The researchers hope to gain new insights that will be of relevance to the development of quantum computers.

Scientists' new approach improves efficiency of solar cells Posted: 25 Oct 2013 06:17 AM PDT Scientists have developed a new method to increase the efficiency of solar cells.

Minuscule bumps improve an anti-reflective coating Posted: 24 Oct 2013 08:41 AM PDT An anti-reflective film that mimics a moth's eye is durable and highly effective, overcoming some of the main barriers to commercialization.
