Struct BcaConfig 

pub struct BcaConfig {
    pub mean_free_path: MeanFreePath,
    pub electronic: ElectronicLoss,

    pub follow_recoils: bool,
    pub primary_cutoff_ev: f64,

Run configuration.

Fields

mean_free_path: MeanFreePath

Free-path convention. Default MeanFreePath::Constant.

electronic: ElectronicLoss

Electronic-loss treatment. Default ElectronicLoss::NonLocal.

weak_collisions: u8

Number of simultaneous weak collisions per collision step, 0..=3 (MeanFreePath::Constant only; see the module docs, “Weak collisions”). Default 0, the single-collision convention of Biersack and Haggmark (1980).

follow_recoils: bool

Follow displaced atoms as full cascades. If false, a displaced atom stops where it was created and its energy counts as rest energy (an ion-only run). Default true.

primary_cutoff_ev: f64

The primary stops when its energy falls below this, eV.

recoil_cutoff_ev: f64

Recoils stop when their energy falls below this, eV. A recoil cutoff above the surface binding energies suppresses sputtering, so keep it below the smallest E_s when sputtering matters (Eckstein 1991).

primary_surface_binding_ev: f64

Planar surface barrier for the primary’s species at both faces, eV. Default 0 (backscattered ions are not bound). Target atoms use the E_s of the material at the face (see Bca::new).

seed: u64

Run seed for crate::rng::stream.

chunk_size: u64

Histories per work chunk for crate::rng::run_particles; fixes the summation order, so keep it independent of the thread count. Default 64.

Implementations

impl BcaConfig

pub fn new(primary_cutoff_ev: f64, recoil_cutoff_ev: f64) -> Self
