Splitting Energy

First-principles calculations are carried out to analyze the variation of the energy gap and the absolute value of the crystal-field splitting energy of wurtzite zinc oxide under uniaxial loading along [0001] direction. The uniaxial loading in [0001] direction is predicted to be more effective to adjust the energy gap than applying the hydrostatic pressure, without changing the direct energy-gap nature. The top of the valence band is sensitive to the uniaxial stress, and the absolute value of the crystal-field splitting energy reaches the minimum when the uniaxial stress is about 2 GPa. The variation in electronic properties originates mainly from the relatively lower density of the valence electrons inc-axis direction.

We have extended the low temperature magnetic anisotropy measurements on single crystals of zinc containing up to 600 p.p.m. manganese from magnetic fields of 9 to 56 kG. The crystal field splitting parameters determined at low magnetic fields also characterizes the magnetic anisotropy at high magnetic fields. Manganese–manganese interaction effects are observed in the magnetic anisotropy at manganese concentrations greater than 300 p.p.m. Low temperature magnetic anisotropy measurements on single crystals of zinc containing up to 164 p.p.m. chromium are reported and indicate a crystal field splitting of 0.16 K for the chromium ion.
