Zincblende and Wurtzite structure band, compatible with structure BAND.

Defines

SQ(x)

short for square of a function

Typedefs

typedef struct ZBBAND ZBBand

structure for Zinc-blende band

typedef struct WZBAND WZBand

struct for Wurtzite band:

This may not be necessary because it’s still a 3 band model with F=0. It’s here to demonstrate how new material can be added.

Functions

numpyint ZBupdateM(const Band *mat, double Eq, const double *xVc, double *m)

Update effective mass of a Zincblende band semiconductor

double ZBNormalize(const Band *mat, double Eq, const double *xVc, double *psi, double xres)

The normalization condition for Zincblende band.

numpyint WZupdateM(const Band *mat, double Eq, const double *xVc, double *m)

Update effective mass of a Wurtzite band semiconductor. Output N.

double WZNormalize(const Band *mat, double Eq, const double *xVc, double *psi, double xres)

The normalization condition for Wurtzite band.
