A data storage unit is disclosed. The data storage unit can comprise a data storage layer having a plurality of data storage areas. Each data storage area can be configured to carry at least one bit of data. An electron beam emitter can be configured to selectively direct a beam of electrons toward the data storage layer to enable one or more of the data storage areas to be read. The data storage layer can further be configured to filter the beam of electrons directed toward the data storage layer according to a state of the data storage area. The data storage unit further comprises a layer adjacent to the data storage layer (LASL) in which carriers are generated in response to the number of electrons reaching the LASL. A detection region can be in carrier communication with the LASL and configured to measure carrier transport in the detection region to determine the state of the storage area.
