LOCAL_BANDGAP

Prints a local bandgap E_gap(r), derived from the local density of states rho(r,E). Details and formulae in the SI of the periodic GW paper (2023). [Edit on GitHub]

Keywords

Keyword descriptions

SECTION_PARAMETERS: enum = HIGH

Lone keyword: SILENT

Usage: silent

Valid values:

  • ON

  • OFF

  • SILENT

  • LOW

  • MEDIUM

  • HIGH

  • DEBUG

Level starting at which this property is printed [Edit on GitHub]

ADD_LAST: enum = NUMERIC

Usage: ADD_LAST (NO|NUMERIC|SYMBOLIC)

Valid values:

  • NO Do not mark last iteration specifically

  • NUMERIC Mark last iteration with its iteration number

  • SYMBOLIC Mark last iteration with lowercase letter l

If the last iteration should be added, and if it should be marked symbolically (with lowercase letter l) or with the iteration number. Not every iteration level is able to identify the last iteration early enough to be able to output. When this keyword is activated all iteration levels are checked for the last iteration step.

COMMON_ITERATION_LEVELS: integer = 3

Usage: COMMON_ITERATION_LEVELS

How many iterations levels should be written in the same file (no extra information about the actual iteration level is written to the file) [Edit on GitHub]

ENERGY_SPACING: real = 3.00000000E-002 [eV]

Usage: ENERGY_SPACING 0.03

Energy spacing of the LDOS for searching the gap. [Edit on GitHub]

ENERGY_WINDOW: real = 6.00000000E+000 [eV]

Usage: ENERGY_WINDOW 6.0

Energy window in the LDOS for searching the gap. [Edit on GitHub]

FILENAME: string = LOCAL_BANDGAP

Usage: FILENAME ./filename

controls part of the filename for output. use __STD_OUT__ (exactly as written here) for the screen or standard logger. use filename to obtain projectname-filename. use ./filename to get filename. A middle name (if present), iteration numbers and extension are always added to the filename. if you want to avoid it use =filename, in this case the filename is always exactly as typed. Please note that this can lead to clashes of filenames. [Edit on GitHub]

LDOS_THRESHOLD_GAP: real = 1.00000000E-001

Usage: LDOS_THRESHOLD_GAP 0.1

Relative LDOS threshold that determines the local bandgap. [Edit on GitHub]

LOG_PRINT_KEY: logical = F

Lone keyword: T

Usage: LOG_PRINT_KEY

This keywords enables the logger for the print_key (a message is printed on screen everytime data, controlled by this print_key, are written) [Edit on GitHub]

STRIDE: integer = 2 2 2

Usage: STRIDE 2 2 2

The stride (X,Y,Z) used to write the cube file (larger values result in smaller cube files). You can provide 3 numbers (for X,Y,Z) or 1 number valid for all components. [Edit on GitHub]

__CONTROL_VAL: integer = 8

hidden parameter that controls storage, printing,… of the print_key [Edit on GitHub]
