Semiconductor lasers able to emit over the full visible color spectrum have a wide range of practical applications such as solid-state lighting, full-color displays, visible color communications, and multi-color fluorescence sensing. To the human eye, light with a mixture of four monochromatic lasers is visually equivalent to a white illuminant. Current...

Background Conventional Si-based metal-oxide-semiconductor field-effect transistors (MOSFETs) are facing fundamental limitations as demands for increased power efficiency and integration density persist. The Boltzmann limit represents the minimum subthreshold change in gate voltage bias (VGS), 60 mV, required to effectuate a one-decade change in the...

According to the World Health Organization, there are hundreds of millions of people suffering from chronic respiratory diseases (CRDs), including asthma, COPD, sleep apnea, pulmonary hypertension and more. Measuring and characterizing lung functionality is an essential step toward diagnosing, monitoring and treating these respiratory conditions. The...
