    • Nano-scale metal contacts for future III-V CMOS 

      Guo, Alex (Massachusetts Institute of Technology, 2012)
      As modem transistors continue to scale down in size, conventional Si CMOS is reaching its physical limits and alternative technologies are needed to extend Moore's law. Among different candidates, MOSFETs with a III-V ...
    • Nano-scale ohmic contacts for III-V MOSFETs 

      Lu, Wenjie (Massachusetts Institute of Technology, 2014)
      As modem silicon CMOS has been scaled down to extremely small dimensions, there is an urgent need for technological innovations of new devices architectures that would allow the continuation of Moore's Law into the future. ...
    • A nanofabricated amplitude-division electron interferometer in a transmission electron microscope 

      Agarwal, Akshay (Massachusetts Institute of Technology, 2016)
      Wavefront-division electron interferometry with the electron biprism has enabled many applications such as electron holography, exit-wave reconstruction, and demonstration of the Aharonov-Bohm effect. However, wavefront-division ...
    • Nanophotonic visible light phased arrays 

      Raval, Manan (Massachusetts Institute of Technology, 2016)
      Previously demonstrated integrated optical phased arrays have primarily been implemented in silicon-based platforms and have therefore been limited to operation at infrared wavelengths, where silicon provides low-loss ...
    • Nanostructured architectures for colloidal quantum dot solar cells 

      Jean, Joel, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2013)
      This thesis introduces a novel ordered bulk heterojunction architecture for colloidal quantum dot (QD) solar cells. Quantum dots are solution-processed nanocrystals whose tunable bandgap energies make them a promising ...
    • Nanostructured Origami (TM) : folding thin films out of the plane of a silicon wafer with highly stressed chromium hinges 

      Arora, William Jay (Massachusetts Institute of Technology, 2005)
      This thesis addresses the construction of complex three-dimensional (3-D) nanostructures using only 2-D, planar nano-fabrication techniques. In the state of the art, multiple 2-D layers are fabricated in series, each ...
    • Nanostructuring magnetic thin films using interference lithography 

      Walsh, Michael E. (Michael Edward), 1975- (Massachusetts Institute of Technology, 2000)
      Proliferation of data caused by rapid increases in computer power and the rise of the internet have caused an acute need for advanced data storage technology. Patterned magnetic media and magneto-resistive random-access ...
    • Narratarium : real-time context-based sound and color extraction from text 

      Peng, Timothy, M. Eng. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2013)
      Narratarium is a system that uses English text or voice input, provided either realtime or off-line, to generate context-specific colors and sound effects. It accomplishes this by employing a variety of machine learning ...
    • Narrated guided tour following and interpretation by an autonomous wheelchair 

      Hemachandra, Sachithra Madhawa (Massachusetts Institute of Technology, 2010)
      This work addresses the fundamental problem of how a robot acquires local knowledge about its environment. The domain that we are concerned with is a speech-commandable robotic wheelchair operating in a home/special care ...
