Fluorescence spectrum observation of single chlorosome at cryogenic temperature

MOSFET Characteristics at Cryogenic Temperature

Efficiency is a large concern in power electronics but size and weight must be taken into consideration as well. Power devices in need of thermal sinks for appropriate performance will affect both size and weight. MOSFET devices are the main components in the power electronics world because of their comparatively promising characteristics in power loss and switching performance. The objective o...

Nonclassical photon statistics in single-molecule fluorescence at room temperature

The fluorescence of single terrylene molecules in a crystalline host is investigated at room temperature by scanning confocal optical microscopy. Photon arrival times are analyzed in terms of interphoton time distributions, second order correlation functions, and the variance of the photon number probability distribution. Antibunching at short times and bunching behavior for longer times is obs...

Single Wall Carbon Nanotubes Based Cryogenic Temperature Sensor Platforms

We present an investigation consisting of single walled carbon nanotubes (SWCNTs) based cryogenic temperature sensors, capable of measuring temperatures in the range of 2-77 K. Carbon nanotubes (CNTs) due to their extremely small size, superior thermal and electrical properties have suggested that it is possible to create devices that will meet necessary requirements for miniaturization and bet...

Observation of CHG Spectrum at UVSOR-II

At synchrotron light sources, the drift of the orbit of the electrons in the storage ring causes a drift of the light source position, which affects user’s experiments. At UVSOR-II, an RF feedback system [1] has been operating to suppress the orbit drift on the horizontal plane caused by the thermal expansion of the storage ring floor. However, on the vertical plane, there’s no system to stabil...
