ovshinsky effect
Very Low (C2+)Exclusively Technical/Specialist
Definition
Meaning
A specific physical phenomenon in amorphous semiconductors where an applied electric field causes a sudden, reversible, and persistent change from a high-resistance state to a low-resistance state.
Named after its discoverer, Stanford R. Ovshinsky, this effect is the foundational principle behind Ovonic Threshold Switching (OTS) and Ovonic Memory Switching (OMS), which are crucial for certain types of non-volatile memory (like phase-change memory) and electrical switches.
Linguistics
Semantic Notes
Refers specifically to the electrical switching phenomenon in chalcogenide glass materials. It is a proper noun (capitalised) and is not a general term. It is synonymous with 'Ovonic switching effect'.
Dialectal Variation
British vs American Usage
Differences
No significant linguistic difference in usage. Both varieties use the term identically in technical literature.
Connotations
None beyond its precise scientific meaning.
Frequency
Extremely rare in both varieties, confined to specialised fields of materials science, physics, and electrical engineering.

Examples
By Part of Speech
adjective
British English
- The Ovshinsky-effect device showed remarkable stability.
- This is an Ovshinsky-effect-based memory cell.
American English
- The Ovshinsky-effect device demonstrated remarkable stability.
- This is a memory cell based on the Ovshinsky effect.
Examples
By CEFR Level
- The Ovshinsky effect is a key principle in some advanced computer memory technologies.
- Scientists studied materials that exhibit the Ovshinsky effect.
- The commercial viability of phase-change memory hinges on the reliable and reproducible manifestation of the Ovshinsky effect in doped chalcogenide alloys.
- Ovshinsky's 1968 paper first delineated the threshold switching phenomenon that would later bear his name.
Learning
Memory Aids
Mnemonic
Think of 'OVen' SHINing a light on a SWITCH. Stanford Ovshinsky discovered a sharp electrical SWITCHing effect in special glass.
Conceptual Metaphor
A BINARY GATE or a SUDDEN COLLAPSE (from a blocking to a conducting state).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводить как «эффект Овшинского» в неспециальных текстах, так как имя собственное сохраняется. Avoid calquing 'effect' as 'воздействие'— here it is strictly 'явление' or 'эффект'.
Common Mistakes
- Misspelling as 'Ovinsky effect' or 'Ovshinsky affect'.
- Using it as a general term for any switching effect.
- Failing to capitalise the name 'Ovshinsky'.

FAQ
Frequently Asked Questions
Not exactly. The Ovshinsky effect (specifically Ovonic Memory Switching) is the fundamental physical phenomenon that enables one type of phase-change memory. Phase-change memory is the device application.
No, only the proper name 'Ovshinsky' is capitalised. The word 'effect' remains in lowercase.
In American English, it is approximately 'ahv-SHIN-skee'. The 'O' is like the 'o' in 'hot' or 'ah' as in 'father'.
No. It is a highly specialised technical term (C2+ level). It is only necessary for learners working in very specific areas of physics or engineering.
