Investigates the semiconducting properties of n- and p-type tungsten diselenide crystals, revealing key findings on their conductivity and energy gap.

Key Points

The aim is to analyze the semiconducting properties of tungsten diselenide (WSe2) single crystals across varying temperatures.
Studied optical absorption, photoconductivity, electrical conductivity, and Hall coefficient over 77°–295°K.
Analyzed p-type WSe2 with hole mobility and carrier concentration at 295°K.
Examined effects of rhenium doping on carrier concentration and mobility for n-type WSe2.
Forbidden energy gap Eg is 1.35 eV at 295°K, with a temperature dependency of dEg/dT = −4.6×10−4 eV/°K.
P-type WSe2 has hole mobility μh ∼ 80 cm2/V·sec and carrier concentration p ∼ 10^16/cc at 295°K.
N-type WSe2 shows carrier concentration n ∼ 10^17/cc and electron mobility μn ∼ 100 cm2/V·sec at 295°K.
