Modification of hydrogen-passivated silicon by a scanning tunneling microscope operating in air
TL;DR: In this paper, the chemical modification of hydrogen-passivated n-Si surfaces by a scanning tunneling microscope (STM) operating in air is reported, and the modified surface regions have been characterized by STM spectroscopy, scanning electron microscopy (SEM), time-of-flight secondary ion mass spectrometry (TOF SIMS), and chemical etch/Nomarski microscopy.
Journal ArticleDOI
Controlling doping and carrier injection in carbon nanotube transistors
TL;DR: In this article, two methods for converting carbon nanotube field effect transistors (CNTFETs) from p-to n-type devices are presented, one involves conventional doping with an electron donor, while the second consists of annealing the contacts in vacuum to remove adsorbed oxygen.
Journal ArticleDOI
Characterisation and modeling of mismatch in MOS transistors for precision analog design
TL;DR: In this paper, a characterization methodology is presented that accurately predicts the mismatch in drain current over a wide operating range using a minimum set of measured data and the physical causes of mismatch are discussed in detail for both p- and n-channel devices.

Organic ternary solar cells: a review.
TL;DR: The novel concept of ternary organic solar cells is a promising candidate to extend the absorption spectra of large bandgap polymers to the near IR region and to enhance light harvesting in single bulk-heterojunction solar cells.
