Abstract :
Pure boron (PureB) chemical-vapor deposition performed at 400°C is applied as a postmetalization process module to fabricate near-ideal p+n photodiodes with nm-thin PureB-only beam-entrance windows. The photodiodes have near-theoretical sensitivity and high stability for optical characterization performed with either UV light down to a wavelength of 270 nm or low-energy electrons down to 200 eV.
