Abstract
Inorganic semiconducting materials such as silicon are used as a host matrix in which quantum dots reside to provide a radiation detector or energy converter. The quantum dot material may be disposed by incorporating materials sensitive to neutron detection such as boron-containing compounds, or the use of methods such as chemical vapor deposition or atomic layer deposition to insert the quantum dot material. Electrodes may be extended deep into the host matrix material to improve efficiency. Likewise, the host matrix may be machined to create pores in the matrix material. Further, amplification and signal-processing structures may be used in close proximity to the radiation-sensitive region of the device.
