摘要： The present invention provides systems, devices, device components and structures for modulating the intensity and/or energies of electrons, including a beam of incident electrons. In some embodiments, for example, the present invention provides nano-structured semiconductor membrane structures capable of generating secondary electron emission. Nano-structured semiconductor membranes of this aspect of the present invention include membranes having an array of nanopillar structures capable of providing electron emission for amplification, filtering and/or detection of incident radiation, for example secondary electron emission and/or field emission. Nano-structured semiconductor membranes of the present invention are useful as converters wherein interaction of incident primary electrons and nanopillars of the nanopillar array generates secondary emission. Nano-structured semiconductor membranes of this aspect of the present invention are also useful as directed charge amplifiers wherein secondary emission from a nanopillar array provides gain functionality for increasing the intensity of radiation comprising incident electrons.

摘要： An active detector and methods for detecting molecules, including large molecules such as proteins and oligonucleotides, at or near room temperature based on the generation of electrons via field emission (FE) and/or secondary electron emission (SEE). The detector comprises a semiconductor membrane having an external surface that is contacted by one or more molecules, and an internal surface having a thin metallic layer or other type of electron emitting layer. The kinetic energy of molecules contacting the semiconductor membrane is transferred through the membrane and induces the emission of electrons from the emitting layer. An electron detector, which optionally includes means for electron amplification, is positioned to detect the emitted electrons.
