New, smaller PMIC chip - CES 2015

submitted by: nsf
A significant amount of real estate inside your cell phone is taken up by a chip called a power management integrated circuit (PMIC). The chip delivers power from the battery to different areas within the phone, an efficient but bulky system. Now, NSF-funded small business Lion Semiconductor has designed a chip that is two to three times smaller than existing ones. A smaller chip means more room for a bigger battery – and longer battery life – or a thinner, smaller device. Wonyoung...

New Paradigm for Solar Energy Conservation Using Semiconductor Nanocrystals

submitted by: icamvid

Victor Kumon gives a talk at the ICAMET 07 conference about the application of carrier multiplication (generatio of multiple electron pairs by a single photon) to solar energy.

Humidity Dependence of Charge Transport in Melanin

submitted by: icamvid

Bernard Mostert gives a talk at the ICAM 2007 conference proposing that at ambient conditions melanin is not an organic semiconductor and that protons are the charge carrier.
