Inductive measurement of optically hyperpolarized phosphorous donor nuclei in an isotopically enriched silicon-28 crystal.

We experimentally demonstrate the first inductive readout of optically hyperpolarized phosphorus-31 donor nuclear spins in an isotopically enriched silicon-28 crystal. The concentration of phosphorus donors in the crystal was 1.5×10(15)  cm(-3), 3 orders of magnitude lower than has previously been detected via direct inductive detection. The signal-to-noise ratio measured in a single free induc...

Silicon Bulk Mobility at High Ambient Temperatures

One of the goals of the PARASITICS project was the evaluation of decisive physical models in the high temperature range (300 K – 700 K) by comparison between simulation and electrical measurements of suitable test structures. Various van der Pauw devices were examined to test the microscopic-based mobility model of Schenk [1]. In order to make the comparison complete, calculated Hall factors as...

Perforated diode neutron detector modules fabricated from high-purity silicon

Compact neutron detectors are being designed and tested for use as low-power real-time personnel dosimeters. The neutron detectors are pin diodes that are mass produced from high-purity Si wafers. Each detector has thousands of circular perforations etched vertically into the device. The perforations are backfilled with LiF to make the pin diodes sensitive to thermal neutrons. The prototype dev...
