bulk characteristics (of a semiconductor material)
The characteristics of a piece of semiconductor material that has uniform properties throughout the whole piece, as measured in those parts of the piece in which the measured value of a characteristic is not modified by the proximity of the boundaries of the piece.
NOTE Bulk characteristics for pieces smaller than required by the definition are those that would be measured for a sufficiently large piece having the same technological properties.
